The synchronous scene, the small screen is consistent as the large screen. With the adjustment of various aspects, such as exposure, focusing, etc., what you see also changes simultaneously. "". In this way, you can't see anything without turning on. It is the most convenient and power -saving to use this viewfinder. Thexicated by the horizons, you can see things without turning, but the errors and income are usually small composition, the composition is large, the difference is larger, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus. Manual adjustment of exposure and so on cannot be obtained intuitively. You have to know what results are taken after shooting. The without the scene, everything depends on the screen, Lenovo S500 is this design. Although it is "what you see is the income", because when taking pictures in the sun, unless you shoot backlight, the shooting object is generally the sun, so the screen is also under the sun, and basically nothing can be seen. If there are people who use the camera, if they are over 40 years old, because the eyes are beginning to be old flowers, the results can not be seen without wearing a flower mirror. It's zoom multiple, zoom multiple, mainly determine the longest focal length, such as 12 times zoom, the longest focal length reaches 420 mm, so that the long -distance camera function is very strong, can shoot long -view, birds, beasts, beauty, etc. Wait. You can get a large sun and moon when shooting the sun and the moon. has no above functions, which has a great impact. There is no good viewfinder, and the success rate of taking photos is greatly reduced. If the zoom multiple is small, you cannot shoot the scenery from a distance. For example, if you want to shoot a beauty, the other party finds that people will look at you, or flatten you directly. At least you get a unnatural expression, and you cannot shoot wild animals. You are close to the birds. Just fly. If it is just a photo of "One Tour", it is not important to have any. DV's viewfinder is needed? On the one hand, the black and white viewfinder can save electricity and extend the battery shooting time. But on the other hand, the color of the black and white landscape is completely lost, and it is a bit difficult in composition and view. As for how to choose it depends on your own preferences. The viewfinder is used for viewing, and taking pictures always have to be viewed. The common is synchronous viewing, beam axis, and screen views.

The viewfinder The viewfinder is to monitor the image part of the image through the eyepiece on the digital camera. The current mirror of the digital camera is only black and white viewer and color viewfinder. But for professional -level digital cameras, it is a black and white landscape, because black and white landscapes are more beneficial to photographers to correctly compose. The digital camera is the same as its liquid crystal display structure. Both use TFT LCD, and the difference is that the size of the two and power consumption.
The general digital camera's viewfinder is relatively small, only enough to close one eye to observe; for some professional models, or some shoulder bracket DVs, its pixels are even better than LCD screens. To be big, this is convenient for the photographer to see the shooting screen.
Compared with its LCD display, the viewfinder has another advantage, that is, power saving. Generally speaking, when the LCD display is turned off, only the viewfinder can be used, which can save at least four points. The power of one time.
The viewer of the digital camera can generally rotate in the vertical direction. There are even 90 degrees of rotation angle, which is more convenient for photographers to shoot while standing in a standing posture. Moreover, most of the viewfinder can change the distance of the eyepiece, which is convenient for photographers with myopia to wear glasses.
In general, for professional photography, the viewfinder is still very important, so we look at those professional DVs, which are very good in the manufacturer of the viewfinder. This is for convenience Designed by professional photography. digital camera D digital camera is also called digital camera. The full English name is Digital Camera, referred to as DC. Digital cameras are products that integrate optical, machinery, and electronic integration. It integrates the conversion, storage and transmission of image information, has the characteristics of digital access mode, interacting with computer and real -time shooting. Digital cameras first appeared in the United States. More than 20 years ago, the United States used it to send photos to the ground through satellites. Later, digital photography turned into civilian use and continued to expand its application scope.
The development of the development process of the digital camera
2005.07.28 11:27:08
It has been developing for nearly 200 years. In these 200 years, the camera has gone through black and white to color, evolved from pure optical and mechanical architecture to optical, mechanical, and electronics. From traditional silver salt film to today's digital memory as a record medium. Looking at the clouds and seeing the clouds, the emergence of digital cameras officially marked the leap -forward development of the camera industry towards the new era of digitalization, and people's image life has also changed completely.
In October 17, 1969, Ball and Smith at the Bell Institute in the United States have announced the invention of "CCD" (charge coupling element). Get widely used. The latest improved editions such as 4 -color CCD, Super CCD, etc. have continued to emerge. Pixels have already spans 10 million pixels, but the imaging effect has also become perfect.
. After more than ten years of continuous development, the DC industry has already gone out of its own child, the design is more mature, the operating function is growing, and with the further reduction of manufacturing costs, the development of such products is developed. It has been revealed that unlimited development signs have been revealed.
In general, the development process of the DC industry for more than ten years has always adhered to the development context of "higher, faster, stronger, and more humane". In today's digital camera market, it will become so prosperous and beautiful. While enjoying the convenience brought by technology, people still can't help but read the bumpy roads that have been traveled at the beginning of the birth of a digital camera. Some classic models that have a significant impact on this industry are still unforgettable.
This-life explosion
The lives suddenly appeared in the Cambrian, and the entire earth became colorful and full of life. Archeologists The reason for its reason has not been given a clear answer. In the 1980s, it was tantamount to the Cambrian of the digital camera industry. In less than ten years, the digital camera quickly broke away from 襁褓 and gradually learned to stagnate. Although the resolution was still very low at that time, the participation of many manufacturers participated Make this industry full of vitality.
Mabika —— the world's first electronic camera that does not need to be sensitive film
November 1973, Sony officially started the research of "electronic eyes" CCD research On the basis of continuous technical accumulation, it launched the world's first electronic camera in the world in 1981, the static video "MABIKA". The camera uses a CCD thin piece of 10 mm × 12 mm with a resolution of only 570 × 490 (279,000) pixels. For the first time, the light signal is changed to electronic signal transmission.
followed closely, and Company Panasonic, Copal, Fuji, Canon, Nikon and other companies also started the development of electronic cameras. From 1984-1986, their own prototype electronic cameras were launched. The outbreak started.
Sony MYC-A7AF —— The first time the digital camera has a pure physical operation method
Sony's hand, it can be seen that the company's market position today is by no means a "virtual name". In 1986, Sony released MyC-A7AF. For the first time, the digital camera had a pure physical operation method. It could record static images on 2-inch plates. Pixel resolution has also expanded to 38 million pixels. Casio VS-101 —— The first CMOS photosensitive device electronic camera
In 1987, Casio first released the VS-101 electronic camera with CMOS photosensitive device on the market, although the resolution can only reach 28 million pixels, , But this is of great significance to the DC industry.
It today, the competition for the orthodox aspects of CMOS and CCDs in digital camera sensor has been settled. In addition to being widely used on the Canon high -end camera today, CMOS has been widely used. CCD regards CCD as the dominant direction of its own products. It is not necessary to deny that the advantages of CMOS have the advantages of full -scale, low energy consumption, etc., but the disadvantages of low dynamic scope cannot not help people "stay away".
The RC-760 ----- The first 600,000 pixel model
wants to obtain the shooting effect close to traditional cameras, improve the CCD pixel resolution counted as calculated The most fundamental solution, but in the early stage of the birth of a digital camera, it is easy to talk about it on the pixel. For a few years, manufacturers have been hovering at a level of 300,000 pixels. It was not until 1988 that Canon launched a 600,000-pixel model RC-760.
The electronic camera uses a 2/3 inch 600 million pixel CCD. The appearance is slightly rigid today, but this is the highest pixel machine at that time. The price is higher than today. It's expensive.
This-dinosaurs are fierce
In long evolution and evolution, life finally gave birth to a more advanced form of life, and the world suddenly became more lively. Woke up. The continuous accumulation of technology in the 1980s finally ushered in the true prosperity of the digital camera industry in the 1990s. Since then, digital cameras have established their basic survival model.
Kodak DCS 100 —— The general mode of digital camera in the world
In 1990, Kodak launched the DCS100 electronic camera, which was the first time in the world to establish a digital camera in the world. General model, since then, this model has become the industry standard.
For professional photographers, if a new machine has their familiar body and control mode, it will undoubtedly become simpler. In order to cater to this consumer psychology, Kodak Company applied to the DCS100 in the well -known Nikon F3 fuselage at the time. Internal functions have made great changes except for focusing screens and roll motors. Nikon lens is really detailed.
The digital SLR uses a 20.5 x 16.4mm CCD with 1.4 million pixels, and the light change multiple is 1.8X. The external storage unit (DSU) is used. DSU is similar to today's camera base. Battery uses battery as a driver energy. The built -in 200MB memory can store 150 unprepared RAW photos.
The view mode is also very primitive compared to today's machine. The photographer can use the optical viewfinder on the camera or the 4 -inch LCD LCD screen on the DSU. But very high -end. The price of this machine at that time was equivalent to 225,000 yuan today, which is really expensive.
In DCS100 was successful, Kodak launched the DCS100 subsequent model DCS200 in 1992. It finally got rid of DSU's burden, and the memory was placed inside the fuselage. The shooting becomes very comfortable.
Neon/Fuji E2/E2S —— The digital SLR
does not matter whether Kodak or Canon, the original tradition was used in the early product design Although the camera's film fuselage, although this can make professional photographers feel the affinity of the product, the product is inevitable to make people feel boring. In 1995, the two giants of Nikon and Fuji joined forces to launch a newly designed E2/E2S. It no longer copied the traditional fuselage of old teeth and adopted an integrated design style, which can easily make people feel refreshing.
The resolution of this digital SLR is only 1.3 million pixels. Compared with the 6 million pixels of the Kodak DCS460 of the same age, it is very different. The most special feature of E2/E2S is that Nikon's newly developed ROS optical system is adopted. Through a set of optical components, the light is projected to the CCD with an area of less than 35mm. The aperture has been severely shrinking, and the quality of imaging has been greatly affected.
The integrated design makes the appearance of this machine look more concise, but the complexity of the internal structure inevitably causes the appearance of the appearance volume, and the total weight also shows signs of out of control. This machine has accumulated a lot of experience for Nikon's digital SLR research and development. After four years of listing, Nikon launched an epoch -making D1, and the Baiji period of the digital camera industry was completely over.
S Jurassic-dangerous jungle
The biological category of Jurassic is already very complete. There is also a very fierce Bawang Dragon. Each animal seems to be more powerful to survive in this world. Only in this way can you be easy to spend in this weak meat and strong jungle.
INkon D1 —— Nikon's first self-developed digital SLR
In June 1999, Nikon finally launched the company's first digital SLR-D1 developed by the company. The price of the Kodak DCS series cameras has launched a new era of digital SLR people.
The body used in this digital SLR is completed by the traditional camera F5, which still maintains a very attractive professional temperament. It has a built-in 2.74 million pixel CCD and ISO's sensitivity is 200-1600. It uses CF card/IBM micro-hard disk as a storage medium. The supported file formats include three types: JPEG, TIFF, and RAW. Essence
In Canon EOS 1D — Canon's digital single hair myth
For a long time, while the pixel resolution competes, the competition of manufacturers in shooting speed is also in full swing. In order to completely surpass the myth created by Nikon D1, Canon launched the EOS 1D dedicated to fast shooting in September 2001, thus overwhelming the Nikon D1 in speed and technical indicators, and achieved a new generation of legends in the DC industry.
The digital SLR has a 4-megapixel resolution, ISO sensitivity is 100-1600, and CF card/IBM microcracks are also used as a storage medium, which is priced at about $ 7,000.
Olympic Bas E-1 —— 4/3 system masterpieces
, just like early notebook manufacturers, in order to create the greatest trouble for the opponent, digital SLR When designing product design, manufacturers must deliberately avoid compatibility with their opponents. In this way, any brand of digital camera components cannot be universal. After the component is damaged, users can only buy product replacement of the same brand. The profit was maximized.
The notebooks today have long been mutually compatible. This can be said to be the increasingly enlightened performance of computer manufacturers, but the change of the digital camera industry is also quietly carried out. In December 2003, Olympus released the E-1 of the "4/3 system" jointly developed by the two companies of Kodak and Fuji.
4/3 system specifies the area of the CCD photosensitive device, the distance between the CCD and the lens, and the diameter of the lens. This is definitely unimaginable in previous products.
e-1 uses a 5-megapixel CCD, the ISO sensitivity range is 100-800, using the CF card as a storage medium, supporting JPEG, RAW, and TIFF file format. At the beginning of the release, the price was as high as 16,000 yuan.
Tun EOS 300D -a generation of civilian Digital SLR King
The digital SLR function is powerful and the picture quality is beautiful, but the high price is that it cannot approach civilians The biggest obstacles of the people. In order to successfully complete the popularity of digital SLR, manufacturers are always digging to find ways to reduce costs. It is with their unremitting efforts that a group of reasonable civilian digital SLR has finally emerged, and the Canon E0S 300D It is undoubtedly a pioneer of this process.
In August 2003, Canon launched an EOS 300D with a plastic body, which integrates the predecessor's EOS-10D CMOS photosensitive device. The original competition pattern of the market.
This camera uses 6.3 million pixels CCD, ISO sensitivity is 100-1600, and CF cards are used as a storage medium. The design applies the three colors of silver, gray, and black, and the overall feeling is pretty good.
2006.5.30 Supplement:
The digital camera is the same as the traditional camera, both in appearance or function. Essence The most obvious difference between the digital camera and the traditional camera is on the storage medium. The digital camera uses disk pads or memory cards that can be recorded to access images. After shooting The online method is transmitted to the computer for processing, and it can also be printed directly from a printer with special functions. The biggest advantage is that when the shooting effect is not satisfactory, you can delete and re -shoot in time. At the same time Generally, you can buy negatives, which can save negative costs and save printed fees at the same time. In terms of processing efficiency, digital cameras have a very large advantage over traditional cameras. Hundreds of photos taken in the past event, if you use traditional cameras, you must wait for the time of rinse and mail, but now, but now As long as the digital camera is passed to the computer through the digital camera, and the email mails can be used to mail it to the participants in real time. Therefore, in this era of efficiency in this thing, it can be said that it is a very convenient image device. one. The viewfinder () is the "window" of the viewer's observation of the scene to shoot. Below we will introduce 4 -digital cameras commonly used. · optical viewfinder
The optical viewfinder on a small digital camera consists of a set of simple optical elements. Connected to the influence of entering the lens. This viewfinder is small, but the biggest problem is that there is a scene error. The viewfinder is usually placed above the lens. The image seen from the optical viewfinder is different from the image projected on the sensor. In short distance shooting, this "vision" is even more obvious. The general optical viewfinder can only allow users to see 80%to 90%of the actual coverage of the lens. If you want to accurately view, it is better to use the LCD that is not spoof. Friends who wear eyes are best to look at whether there is a refractive adjustment next to the viewfinder when using the optical viewfinder.
· The LCD view of the non -professional digital camera
LCD views of small digital cameras allow users to observe the image they want to shoot in real time. This image and lens are projected on the CCD The image is the same, and there will be no visual difference. This way of view is also called "TTL" (Through-The-Lens) through the lens. But we know that using LCD is very power -consuming, and when the sun is fierce, it is difficult for us to see the picture on LCD. This prompt us to use optical viewfinder or the EVF viewfinder mentioned below. In addition, the LCD on the digital SLR is not used for viewing. It can only allow users to watch photos and operating menus on LCD after shooting. Of course, DSLR has its own unique way of view, which will also be introduced below.
· Digital SLR optical viewfinder (TTL)
The digital SLR that uses an optical viewfinder does not have a viewfinder, because its optical viewfinder is better than small than small The precision of the digital camera, and its principle is to connect a reflector and diamond mirror onto the sensor. The image that the lens is projected on the sensor is the image seen on the TTL. When the photographer presses the shutter, the reflector will bounce up, the light enters the sensor through the lens, and the sensor begins to expose. Due to the limitation of the sensor, most of the LCDs of the digital SLR can only be used to watch photos and cannot be used for viewing. There are usually a small LCD display camera for various settings and states next to the DSLR optical viewfinder, such as aperture shutter, exposure compensation, and white balance.
· EVF electronic view on the small digital camera
The electronic scene is actually transmitting the screen on the LCD to the electronic viewfinder of the digital camera, so I saw it from EVF The image projected to the CCD is the same as the lens, and it is synchronized with the image on the LCD. EVF is fundamentally a small LCD above the lens (about 0.5 "and the pixel is about 235,000). . EVF absorbs the many advantages of digital SLR TTL viewfinder. For example, there is no vision, but it is impossible for the camera with EVF to install the optical viewfinder in one fell swoop.
Whether the DV's viewfinder needs is a question of "benevolent and wise". On the one hand, the black and white viewfinder can save electricity and extend the battery shooting time. But on the other hand, the color of the black and white landscape is completely lost, and it is a bit difficult in composition and view. As for how to choose it depends on your own preferences. The viewfinder is used for viewing, and taking pictures always have to be viewed. The common is synchronous viewing, beam axis, and screen views. The synchronous scene, the small screen is consistent as the large screen. With the adjustment of various aspects, such as exposure, focusing, etc., what you see also changes simultaneously. "". In this way, you can't see anything without turning on. It is the most convenient and power -saving to use this viewfinder. Thexicated by the horizons, you can see things without turning, but the errors and income are usually small composition, the composition is large, the difference is larger, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus. Manual adjustment of exposure and so on cannot be obtained intuitively. You have to know what results are taken after shooting. The without the scene, everything depends on the screen, Lenovo S500 is this design. Although it is "what you see is the income", because when taking pictures in the sun, unless you shoot backlight, the shooting object is generally the sun, so the screen is also under the sun, and basically nothing can be seen. If there are people who use the camera, if they are over 40 years old, because the eyes are beginning to be old flowers, the results can not be seen without wearing a flower mirror. It's zoom multiple, zoom multiple, mainly determine the longest focal length, such as 12 times zoom, the longest focal length reaches 420 mm, so that the long -distance camera function is very strong, can shoot long -view, birds, beasts, beauty, etc. Wait. You can get a large sun and moon when shooting the sun and the moon. has no above functions, which has a great impact. There is no good viewfinder, and the success rate of taking photos is greatly reduced. If the zoom multiple is small, you cannot shoot the scenery from a distance. For example, if you want to shoot a beauty, the other party finds that people will look at you, or flatten you directly. At least you get a unnatural expression, and you cannot shoot wild animals. You are close to the birds. Just fly. If it is just a photo of "One Tour", it is not important to have any.
The viewfinder The viewfinder is to monitor the image part of the image through the eyepiece on the digital camera. The current mirror of the digital camera is only black and white viewer and color viewfinder. But for professional -level digital cameras, it is a black and white landscape, because black and white landscapes are more beneficial to photographers to correctly compose. The digital camera is the same as its liquid crystal display structure. Both use TFT LCD, and the difference is that the size of the two and power consumption.

Moreover, most of the viewfinder can change the distance of the eyepiece, which is convenient for photographers with myopia to wear glasses.
In general, for professional photography, the viewfinder is still very important, so we look at those professional DVs, which are very good in the manufacturer of the viewfinder. This is for convenience Designed by professional photography. digital camera D digital camera is also called digital camera. The full English name is Digital Camera, referred to as DC.

It no longer copied the traditional fuselage of old teeth and adopted an integrated design style, which can easily make people feel refreshing.
The resolution of this digital SLR is only 1.3 million pixels. Compared with the 6 million pixels of the Kodak DCS460 of the same age, it is very different. The most special feature of E2/E2S is that Nikon's newly developed ROS optical system is adopted. Through a set of optical components, the light is projected to the CCD with an area of less than 35mm. The aperture has been severely shrinking, and the quality of imaging has been greatly affected.
The integrated design makes the appearance of this machine look more concise, but the complexity of the internal structure inevitably causes the appearance of the appearance volume, and the total weight also shows signs of out of control. This machine has accumulated a lot of experience for Nikon's digital SLR research and development. After four years of listing, Nikon launched an epoch -making D1, and the Baiji period of the digital camera industry was completely over.

The biological category of Jurassic is already very complete. There is also a very fierce Bawang Dragon. Each animal seems to be more powerful to survive in this world. Only in this way can you be easy to spend in this weak meat and strong jungle.
INkon D1 —— Nikon's first self-developed digital SLR
In June 1999, Nikon finally launched the company's first digital SLR-D1 developed by the company. The price of the Kodak DCS series cameras has launched a new era of digital SLR people.
The body used in this digital SLR is completed by the traditional camera F5, which still maintains a very attractive professional temperament. It has a built-in 2.74 million pixel CCD and ISO's sensitivity is 200-1600. It uses CF card/IBM micro-hard disk as a storage medium. The supported file formats include three types: JPEG, TIFF, and RAW. Essence
In Canon EOS 1D — Canon's digital single hair myth
For a long time, while the pixel resolution competes, the competition of manufacturers in shooting speed is also in full swing. In order to completely surpass the myth created by Nikon D1, Canon launched the EOS 1D dedicated to fast shooting in September 2001, thus overwhelming the Nikon D1 in speed and technical indicators, and achieved a new generation of legends in the DC industry.
The digital SLR has a 4-megapixel resolution, ISO sensitivity is 100-1600, and CF card/IBM microcracks are also used as a storage medium, which is priced at about $ 7,000.
Olympic Bas E-1 —— 4/3 system masterpieces
, just like early notebook manufacturers, in order to create the greatest trouble for the opponent, digital SLR When designing product design, manufacturers must deliberately avoid compatibility with their opponents. In this way, any brand of digital camera components cannot be universal. After the component is damaged, users can only buy product replacement of the same brand. The profit was maximized.
The notebooks today have long been mutually compatible. This can be said to be the increasingly enlightened performance of computer manufacturers, but the change of the digital camera industry is also quietly carried out. In December 2003, Olympus released the E-1 of the "4/3 system" jointly developed by the two companies of Kodak and Fuji.
4/3 system specifies the area of the CCD photosensitive device, the distance between the CCD and the lens, and the diameter of the lens. This is definitely unimaginable in previous products.
e-1 uses a 5-megapixel CCD, the ISO sensitivity range is 100-800, using the CF card as a storage medium, supporting JPEG, RAW, and TIFF file format. At the beginning of the release, the price was as high as 16,000 yuan.
Tun EOS 300D -a generation of civilian Digital SLR King
The digital SLR function is powerful and the picture quality is beautiful, but the high price is that it cannot approach civilians The biggest obstacles of the people. In order to successfully complete the popularity of digital SLR, manufacturers are always digging to find ways to reduce costs. It is with their unremitting efforts that a group of reasonable civilian digital SLR has finally emerged, and the Canon E0S 300D It is undoubtedly a pioneer of this process.
In August 2003, Canon launched an EOS 300D with a plastic body, which integrates the predecessor's EOS-10D CMOS photosensitive device. The original competition pattern of the market.
This camera uses 6.3 million pixels CCD, ISO sensitivity is 100-1600, and CF cards are used as a storage medium. The design applies the three colors of silver, gray, and black, and the overall feeling is pretty good.
2006.5.30 Supplement:
The digital camera is the same as the traditional camera, both in appearance or function. Essence The most obvious difference between the digital camera and the traditional camera is on the storage medium. The digital camera uses disk pads or memory cards that can be recorded to access images. After shooting The online method is transmitted to the computer for processing, and it can also be printed directly from a printer with special functions. The biggest advantage is that when the shooting effect is not satisfactory, you can delete and re -shoot in time. At the same time Generally, you can buy negatives, which can save negative costs and save printed fees at the same time. In terms of processing efficiency, digital cameras have a very large advantage over traditional cameras. Hundreds of photos taken in the past event, if you use traditional cameras, you must wait for the time of rinse and mail, but now, but now As long as the digital camera is passed to the computer through the digital camera, and the email mails can be used to mail it to the participants in real time. Therefore, in this era of efficiency in this thing, it can be said that it is a very convenient image device. one
Whether the DV's viewfinder needs is a question of "benevolent and wise". On the one hand, the black and white viewfinder can save electricity and extend the battery shooting time. But on the other hand, the color of the black and white landscape is completely lost, and it is a bit difficult in composition and view. As for how to choose it depends on your own preferences. The viewfinder is used for viewing, and taking pictures always have to be viewed. The common is synchronous viewing, beam axis, and screen views. The synchronous scene, the small screen is consistent as the large screen. With the adjustment of various aspects, such as exposure, focusing, etc., what you see also changes simultaneously. "". In this way, you can't see anything without turning on. It is the most convenient and power -saving to use this viewfinder. Thexicated by the horizons, you can see things without turning, but the errors and income are usually small composition, the composition is large, the difference is larger, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus. Manual adjustment of exposure and so on cannot be obtained intuitively. You have to know what results are taken after shooting. The without the scene, everything depends on the screen, Lenovo S500 is this design. Although it is "what you see is the income", because when taking pictures in the sun, unless you shoot backlight, the shooting object is generally the sun, so the screen is also under the sun, and basically nothing can be seen. If there are people who use the camera, if they are over 40 years old, because the eyes are beginning to be old flowers, the results can not be seen without wearing a flower mirror. It's zoom multiple, zoom multiple, mainly determine the longest focal length, such as 12 times zoom, the longest focal length reaches 420 mm, so that the long -distance camera function is very strong, can shoot long -view, birds, beasts, beauty, etc. Wait. You can get a large sun and moon when shooting the sun and the moon. has no above functions, which has a great impact. There is no good viewfinder, and the success rate of taking photos is greatly reduced. If the zoom multiple is small, you cannot shoot the scenery from a distance. For example, if you want to shoot a beauty, the other party finds that people will look at you, or flatten you directly. At least you get a unnatural expression, and you cannot shoot wild animals. You are close to the birds. Just fly. If it is just a photo of "One Tour", it is not important to have any.
The viewfinder The viewfinder is to monitor the image part of the image through the eyepiece on the digital camera. The current mirror of the digital camera is only black and white viewer and color viewfinder. But for professional -level digital cameras, it is a black and white landscape, because black and white landscapes are more beneficial to photographers to correctly compose. The digital camera is the same as its liquid crystal display structure. Both use TFT LCD, and the difference is that the size of the two and power consumption.
The general digital camera's viewfinder is relatively small, only enough to close one eye to observe; for some professional models, or some shoulder bracket DVs, its pixels are even better than LCD screens. To be big, this is convenient for the photographer to see the shooting screen.
Compared with its LCD display, the viewfinder has another advantage, that is, power saving. Generally speaking, when the LCD display is turned off, only the viewfinder can be used, which can save at least four points. The power of one time.
The viewer of the digital camera can generally rotate in the vertical direction. There are even 90 degrees of rotation angle, which is more convenient for photographers to shoot while standing in a standing posture. Moreover, most of the viewfinder can change the distance of the eyepiece, which is convenient for photographers with myopia to wear glasses.
In general, for professional photography, the viewfinder is still very important, so we look at those professional DVs, which are very good in the manufacturer of the viewfinder. This is for convenience Designed by professional photography. digital camera D digital camera is also called digital camera. The full English name is Digital Camera, referred to as DC. Digital cameras are products that integrate optical, machinery, and electronic integration. It integrates the conversion, storage and transmission of image information, has the characteristics of digital access mode, interacting with computer and real -time shooting. Digital cameras first appeared in the United States. More than 20 years ago, the United States used it to send photos to the ground through satellites. Later, digital photography turned into civilian use and continued to expand its application scope.
The development of the development process of the digital camera
2005.07.28 11:27:08
It has been developing for nearly 200 years. In these 200 years, the camera has gone through black and white to color, evolved from pure optical and mechanical architecture to optical, mechanical, and electronics. From traditional silver salt film to today's digital memory as a record medium. Looking at the clouds and seeing the clouds, the emergence of digital cameras officially marked the leap -forward development of the camera industry towards the new era of digitalization, and people's image life has also changed completely.
In October 17, 1969, Ball and Smith at the Bell Institute in the United States have announced the invention of "CCD" (charge coupling element). Get widely used. The latest improved editions such as 4 -color CCD, Super CCD, etc. have continued to emerge. Pixels have already spans 10 million pixels, but the imaging effect has also become perfect.
. After more than ten years of continuous development, the DC industry has already gone out of its own child, the design is more mature, the operating function is growing, and with the further reduction of manufacturing costs, the development of such products is developed. It has been revealed that unlimited development signs have been revealed.
In general, the development process of the DC industry for more than ten years has always adhered to the development context of "higher, faster, stronger, and more humane". In today's digital camera market, it will become so prosperous and beautiful. While enjoying the convenience brought by technology, people still can't help but read the bumpy roads that have been traveled at the beginning of the birth of a digital camera. Some classic models that have a significant impact on this industry are still unforgettable.
This-life explosion
The lives suddenly appeared in the Cambrian, and the entire earth became colorful and full of life. Archeologists The reason for its reason has not been given a clear answer. In the 1980s, it was tantamount to the Cambrian of the digital camera industry. In less than ten years, the digital camera quickly broke away from 襁褓 and gradually learned to stagnate. Although the resolution was still very low at that time, the participation of many manufacturers participated Make this industry full of vitality.
Mabika —— the world's first electronic camera that does not need to be sensitive film
November 1973, Sony officially started the research of "electronic eyes" CCD research On the basis of continuous technical accumulation, it launched the world's first electronic camera in the world in 1981, the static video "MABIKA". The camera uses a CCD thin piece of 10 mm × 12 mm with a resolution of only 570 × 490 (279,000) pixels. For the first time, the light signal is changed to electronic signal transmission.
followed closely, and Company Panasonic, Copal, Fuji, Canon, Nikon and other companies also started the development of electronic cameras. From 1984-1986, their own prototype electronic cameras were launched. The outbreak started.
Sony MYC-A7AF —— The first time the digital camera has a pure physical operation method
Sony's hand, it can be seen that the company's market position today is by no means a "virtual name". In 1986, Sony released MyC-A7AF. For the first time, the digital camera had a pure physical operation method. It could record static images on 2-inch plates. Pixel resolution has also expanded to 38 million pixels. Casio VS-101 —— The first CMOS photosensitive device electronic camera
In 1987, Casio first released the VS-101 electronic camera with CMOS photosensitive device on the market, although the resolution can only reach 28 million pixels, , But this is of great significance to the DC industry.
It today, the competition for the orthodox aspects of CMOS and CCDs in digital camera sensor has been settled. In addition to being widely used on the Canon high -end camera today, CMOS has been widely used. CCD regards CCD as the dominant direction of its own products. It is not necessary to deny that the advantages of CMOS have the advantages of full -scale, low energy consumption, etc., but the disadvantages of low dynamic scope cannot not help people "stay away".
The RC-760 ----- The first 600,000 pixel model
wants to obtain the shooting effect close to traditional cameras, improve the CCD pixel resolution counted as calculated The most fundamental solution, but in the early stage of the birth of a digital camera, it is easy to talk about it on the pixel. For a few years, manufacturers have been hovering at a level of 300,000 pixels. It was not until 1988 that Canon launched a 600,000-pixel model RC-760.
The electronic camera uses a 2/3 inch 600 million pixel CCD. The appearance is slightly rigid today, but this is the highest pixel machine at that time. The price is higher than today. It's expensive.
This-dinosaurs are fierce
In long evolution and evolution, life finally gave birth to a more advanced form of life, and the world suddenly became more lively. Woke up. The continuous accumulation of technology in the 1980s finally ushered in the true prosperity of the digital camera industry in the 1990s. Since then, digital cameras have established their basic survival model.
Kodak DCS 100 —— The general mode of digital camera in the world
In 1990, Kodak launched the DCS100 electronic camera, which was the first time in the world to establish a digital camera in the world. General model, since then, this model has become the industry standard.
For professional photographers, if a new machine has their familiar body and control mode, it will undoubtedly become simpler. In order to cater to this consumer psychology, Kodak Company applied to the DCS100 in the well -known Nikon F3 fuselage at the time. Internal functions have made great changes except for focusing screens and roll motors. Nikon lens is really detailed.
The digital SLR uses a 20.5 x 16.4mm CCD with 1.4 million pixels, and the light change multiple is 1.8X. The external storage unit (DSU) is used. DSU is similar to today's camera base. Battery uses battery as a driver energy. The built -in 200MB memory can store 150 unprepared RAW photos.
The view mode is also very primitive compared to today's machine. The photographer can use the optical viewfinder on the camera or the 4 -inch LCD LCD screen on the DSU. But very high -end. The price of this machine at that time was equivalent to 225,000 yuan today, which is really expensive.
In DCS100 was successful, Kodak launched the DCS100 subsequent model DCS200 in 1992. It finally got rid of DSU's burden, and the memory was placed inside the fuselage. The shooting becomes very comfortable.
Neon/Fuji E2/E2S —— The digital SLR
does not matter whether Kodak or Canon, the original tradition was used in the early product design Although the camera's film fuselage, although this can make professional photographers feel the affinity of the product, the product is inevitable to make people feel boring.

In October 17, 1969, Ball and Smith at the Bell Institute in the United States have announced the invention of "CCD" (charge coupling element). Get widely used. The latest improved editions such as 4 -color CCD, Super CCD, etc. have continued to emerge. Pixels have already spans 10 million pixels, but the imaging effect has also become perfect.
. After more than ten years of continuous development, the DC industry has already gone out of its own child, the design is more mature, the operating function is growing, and with the further reduction of manufacturing costs, the development of such products is developed. It has been revealed that unlimited development signs have been revealed.
In general, the development process of the DC industry for more than ten years has always adhered to the development context of "higher, faster, stronger, and more humane". In today's digital camera market, it will become so prosperous and beautiful. While enjoying the convenience brought by technology, people still can't help but read the bumpy roads that have been traveled at the beginning of the birth of a digital camera. Some classic models that have a significant impact on this industry are still unforgettable.
This-life explosion
The lives suddenly appeared in the Cambrian, and the entire earth became colorful and full of life. Archeologists The reason for its reason has not been given a clear answer. In the 1980s, it was tantamount to the Cambrian of the digital camera industry. In less than ten years, the digital camera quickly broke away from 襁褓 and gradually learned to stagnate. Although the resolution was still very low at that time, the participation of many manufacturers participated Make this industry full of vitality.
Mabika —— the world's first electronic camera that does not need to be sensitive film
November 1973, Sony officially started the research of "electronic eyes" CCD research On the basis of continuous technical accumulation, it launched the world's first electronic camera in the world in 1981, the static video "MABIKA". The camera uses a CCD thin piece of 10 mm × 12 mm with a resolution of only 570 × 490 (279,000) pixels. For the first time, the light signal is changed to electronic signal transmission.
followed closely, and Company Panasonic, Copal, Fuji, Canon, Nikon and other companies also started the development of electronic cameras. From 1984-1986, their own prototype electronic cameras were launched. The outbreak started.
Sony MYC-A7AF —— The first time the digital camera has a pure physical operation method
Sony's hand, it can be seen that the company's market position today is by no means a "virtual name". In 1986, Sony released MyC-A7AF. For the first time, the digital camera had a pure physical operation method. It could record static images on 2-inch plates. Pixel resolution has also expanded to 38 million pixels. Casio VS-101 —— The first CMOS photosensitive device electronic camera
In 1987, Casio first released the VS-101 electronic camera with CMOS photosensitive device on the market, although the resolution can only reach 28 million pixels, , But this is of great significance to the DC industry.
It today, the competition for the orthodox aspects of CMOS and CCDs in digital camera sensor has been settled. In addition to being widely used on the Canon high -end camera today, CMOS has been widely used. CCD regards CCD as the dominant direction of its own products. It is not necessary to deny that the advantages of CMOS have the advantages of full -scale, low energy consumption, etc., but the disadvantages of low dynamic scope cannot not help people "stay away".
The RC-760 ----- The first 600,000 pixel model
wants to obtain the shooting effect close to traditional cameras, improve the CCD pixel resolution counted as calculated The most fundamental solution, but in the early stage of the birth of a digital camera, it is easy to talk about it on the pixel. For a few years, manufacturers have been hovering at a level of 300,000 pixels. It was not until 1988 that Canon launched a 600,000-pixel model RC-760.
The electronic camera uses a 2/3 inch 600 million pixel CCD. The appearance is slightly rigid today, but this is the highest pixel machine at that time. The price is higher than today. It's expensive.
This-dinosaurs are fierce
In long evolution and evolution, life finally gave birth to a more advanced form of life, and the world suddenly became more lively. Woke up. The continuous accumulation of technology in the 1980s finally ushered in the true prosperity of the digital camera industry in the 1990s. Since then, digital cameras have established their basic survival model.
Kodak DCS 100 —— The general mode of digital camera in the world
In 1990, Kodak launched the DCS100 electronic camera, which was the first time in the world to establish a digital camera in the world. General model, since then, this model has become the industry standard.
For professional photographers, if a new machine has their familiar body and control mode, it will undoubtedly become simpler. In order to cater to this consumer psychology, Kodak Company applied to the DCS100 in the well -known Nikon F3 fuselage at the time. Internal functions have made great changes except for focusing screens and roll motors. Nikon lens is really detailed.
The digital SLR uses a 20.5 x 16.4mm CCD with 1.4 million pixels, and the light change multiple is 1.8X. The external storage unit (DSU) is used. DSU is similar to today's camera base. Battery uses battery as a driver energy. The built -in 200MB memory can store 150 unprepared RAW photos.
The view mode is also very primitive compared to today's machine. The photographer can use the optical viewfinder on the camera or the 4 -inch LCD LCD screen on the DSU. But very high -end. The price of this machine at that time was equivalent to 225,000 yuan today, which is really expensive.
In DCS100 was successful, Kodak launched the DCS100 subsequent model DCS200 in 1992. It finally got rid of DSU's burden, and the memory was placed inside the fuselage. The shooting becomes very comfortable.
Neon/Fuji E2/E2S —— The digital SLR
does not matter whether Kodak or Canon, the original tradition was used in the early product design Although the camera's film fuselage, although this can make professional photographers feel the affinity of the product, the product is inevitable to make people feel boring. In 1995, the two giants of Nikon and Fuji joined forces to launch a newly designed E2/E2S. It no longer copied the traditional fuselage of old teeth and adopted an integrated design style, which can easily make people feel refreshing.
The resolution of this digital SLR is only 1.3 million pixels. Compared with the 6 million pixels of the Kodak DCS460 of the same age, it is very different. The most special feature of E2/E2S is that Nikon's newly developed ROS optical system is adopted. Through a set of optical components, the light is projected to the CCD with an area of less than 35mm. The aperture has been severely shrinking, and the quality of imaging has been greatly affected.
The integrated design makes the appearance of this machine look more concise, but the complexity of the internal structure inevitably causes the appearance of the appearance volume, and the total weight also shows signs of out of control. This machine has accumulated a lot of experience for Nikon's digital SLR research and development. After four years of listing, Nikon launched an epoch -making D1, and the Baiji period of the digital camera industry was completely over.
S Jurassic-dangerous jungle
The biological category of Jurassic is already very complete. There is also a very fierce Bawang Dragon. Each animal seems to be more powerful to survive in this world. Only in this way can you be easy to spend in this weak meat and strong jungle.
INkon D1 —— Nikon's first self-developed digital SLR
In June 1999, Nikon finally launched the company's first digital SLR-D1 developed by the company. The price of the Kodak DCS series cameras has launched a new era of digital SLR people.
The body used in this digital SLR is completed by the traditional camera F5, which still maintains a very attractive professional temperament. It has a built-in 2.74 million pixel CCD and ISO's sensitivity is 200-1600. It uses CF card/IBM micro-hard disk as a storage medium. The supported file formats include three types: JPEG, TIFF, and RAW. Essence
In Canon EOS 1D — Canon's digital single hair myth
For a long time, while the pixel resolution competes, the competition of manufacturers in shooting speed is also in full swing. In order to completely surpass the myth created by Nikon D1, Canon launched the EOS 1D dedicated to fast shooting in September 2001, thus overwhelming the Nikon D1 in speed and technical indicators, and achieved a new generation of legends in the DC industry.
The digital SLR has a 4-megapixel resolution, ISO sensitivity is 100-1600, and CF card/IBM microcracks are also used as a storage medium, which is priced at about $ 7,000.
Olympic Bas E-1 —— 4/3 system masterpieces
, just like early notebook manufacturers, in order to create the greatest trouble for the opponent, digital SLR When designing product design, manufacturers must deliberately avoid compatibility with their opponents. In this way, any brand of digital camera components cannot be universal. After the component is damaged, users can only buy product replacement of the same brand. The profit was maximized.
The notebooks today have long been mutually compatible. This can be said to be the increasingly enlightened performance of computer manufacturers, but the change of the digital camera industry is also quietly carried out. In December 2003, Olympus released the E-1 of the "4/3 system" jointly developed by the two companies of Kodak and Fuji.
4/3 system specifies the area of the CCD photosensitive device, the distance between the CCD and the lens, and the diameter of the lens. This is definitely unimaginable in previous products.
e-1 uses a 5-megapixel CCD, the ISO sensitivity range is 100-800, using the CF card as a storage medium, supporting JPEG, RAW, and TIFF file format. At the beginning of the release, the price was as high as 16,000 yuan.
Tun EOS 300D -a generation of civilian Digital SLR King
The digital SLR function is powerful and the picture quality is beautiful, but the high price is that it cannot approach civilians The biggest obstacles of the people. In order to successfully complete the popularity of digital SLR, manufacturers are always digging to find ways to reduce costs. It is with their unremitting efforts that a group of reasonable civilian digital SLR has finally emerged, and the Canon E0S 300D It is undoubtedly a pioneer of this process.
In August 2003, Canon launched an EOS 300D with a plastic body, which integrates the predecessor's EOS-10D CMOS photosensitive device. The original competition pattern of the market.
This camera uses 6.3 million pixels CCD, ISO sensitivity is 100-1600, and CF cards are used as a storage medium. The design applies the three colors of silver, gray, and black, and the overall feeling is pretty good.
2006.5.30 Supplement:
The digital camera is the same as the traditional camera, both in appearance or function. Essence The most obvious difference between the digital camera and the traditional camera is on the storage medium. The digital camera uses disk pads or memory cards that can be recorded to access images. After shooting The online method is transmitted to the computer for processing, and it can also be printed directly from a printer with special functions. The biggest advantage is that when the shooting effect is not satisfactory, you can delete and re -shoot in time. At the same time Generally, you can buy negatives, which can save negative costs and save printed fees at the same time. In terms of processing efficiency, digital cameras have a very large advantage over traditional cameras. Hundreds of photos taken in the past event, if you use traditional cameras, you must wait for the time of rinse and mail, but now, but now As long as the digital camera is passed to the computer through the digital camera, and the email mails can be used to mail it to the participants in real time. Therefore, in this era of efficiency in this thing, it can be said that it is a very convenient image device. one.
The viewfinder () is the "window" of the viewer's observation of the scene to shoot. Below we will introduce 4 -digital cameras commonly used.
· optical viewfinder
The optical viewfinder on a small digital camera consists of a set of simple optical elements. Connected to the influence of entering the lens. This viewfinder is small, but the biggest problem is that there is a scene error. The viewfinder is usually placed above the lens. The image seen from the optical viewfinder is different from the image projected on the sensor. In short distance shooting, this "vision" is even more obvious. The general optical viewfinder can only allow users to see 80%to 90%of the actual coverage of the lens. If you want to accurately view, it is better to use the LCD that is not spoof. Friends who wear eyes are best to look at whether there is a refractive adjustment next to the viewfinder when using the optical viewfinder.
· The LCD view of the non -professional digital camera
LCD views of small digital cameras allow users to observe the image they want to shoot in real time. This image and lens are projected on the CCD The image is the same, and there will be no visual difference. This way of view is also called "TTL" (Through-The-Lens) through the lens. But we know that using LCD is very power -consuming, and when the sun is fierce, it is difficult for us to see the picture on LCD. This prompt us to use optical viewfinder or the EVF viewfinder mentioned below. In addition, the LCD on the digital SLR is not used for viewing. It can only allow users to watch photos and operating menus on LCD after shooting. Of course, DSLR has its own unique way of view, which will also be introduced below.
· Digital SLR optical viewfinder (TTL)
The digital SLR that uses an optical viewfinder does not have a viewfinder, because its optical viewfinder is better than small than small The precision of the digital camera, and its principle is to connect a reflector and diamond mirror onto the sensor. The image that the lens is projected on the sensor is the image seen on the TTL. When the photographer presses the shutter, the reflector will bounce up, the light enters the sensor through the lens, and the sensor begins to expose. Due to the limitation of the sensor, most of the LCDs of the digital SLR can only be used to watch photos and cannot be used for viewing. There are usually a small LCD display camera for various settings and states next to the DSLR optical viewfinder, such as aperture shutter, exposure compensation, and white balance.
· EVF electronic view on the small digital camera
The electronic scene is actually transmitting the screen on the LCD to the electronic viewfinder of the digital camera, so I saw it from EVF The image projected to the CCD is the same as the lens, and it is synchronized with the image on the LCD. EVF is fundamentally a small LCD above the lens (about 0.5 "and the pixel is about 235,000). . EVF absorbs the many advantages of digital SLR TTL viewfinder. For example, there is no vision, but it is impossible for the camera with EVF to install the optical viewfinder in one fell swoop.
Whether the DV's viewfinder needs is a question of "benevolent and wise". On the one hand, the black and white viewfinder can save electricity and extend the battery shooting time. But on the other hand, the color of the black and white landscape is completely lost, and it is a bit difficult in composition and view. As for how to choose it depends on your own preferences.
The viewfinder is used for viewing, and taking pictures always have to be viewed. The common is synchronous viewing, beam axis, and screen views.
The synchronous scene, the small screen is consistent as the large screen. With the adjustment of various aspects, such as exposure, focusing, etc., what you see also changes simultaneously. "". In this way, you can't see anything without turning on. It is the most convenient and power -saving to use this viewfinder.
Thexicated by the horizons, you can see things without turning, but the errors and income are usually small composition, the composition is large, the difference is larger, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus. Manual adjustment of exposure and so on cannot be obtained intuitively. You have to know what results are taken after shooting.
The without the scene, everything depends on the screen, Lenovo S500 is this design. Although it is "what you see is the income", because when taking pictures in the sun, unless you shoot backlight, the shooting object is generally the sun, so the screen is also under the sun, and basically nothing can be seen. If there are people who use the camera, if they are over 40 years old, because the eyes are beginning to be old flowers, the results can not be seen without wearing a flower mirror.
It's zoom multiple, zoom multiple, mainly determine the longest focal length, such as 12 times zoom, the longest focal length reaches 420 mm, so that the long -distance camera function is very strong, can shoot long -view, birds, beasts, beauty, etc. Wait. You can get a large sun and moon when shooting the sun and the moon.
has no above functions, which has a great impact. There is no good viewfinder, and the success rate of taking photos is greatly reduced. If the zoom multiple is small, you cannot shoot the scenery from a distance. For example, if you want to shoot a beauty, the other party finds that people will look at you, or flatten you directly. At least you get a unnatural expression, and you cannot shoot wild animals. You are close to the birds. Just fly. If it is just a photo of "One Tour", it is not important to have any.
The viewfinder
The viewfinder is to monitor the image part of the image through the eyepiece on the digital camera. The current mirror of the digital camera is only black and white viewer and color viewfinder. But for professional -level digital cameras, it is a black and white landscape, because black and white landscapes are more beneficial to photographers to correctly compose. The digital camera is the same as its liquid crystal display structure. Both use TFT LCD, and the difference is that the size of the two and power consumption.
The general digital camera's viewfinder is relatively small, only enough to close one eye to observe; for some professional models, or some shoulder bracket DVs, its pixels are even better than LCD screens. To be big, this is convenient for the photographer to see the shooting screen.
Compared with its LCD display, the viewfinder has another advantage, that is, power saving. Generally speaking, when the LCD display is turned off, only the viewfinder can be used, which can save at least four points. The power of one time.
The viewer of the digital camera can generally rotate in the vertical direction. There are even 90 degrees of rotation angle, which is more convenient for photographers to shoot while standing in a standing posture. Moreover, most of the viewfinder can change the distance of the eyepiece, which is convenient for photographers with myopia to wear glasses.
In general, for professional photography, the viewfinder is still very important, so we look at those professional DVs, which are very good in the manufacturer of the viewfinder. This is for convenience Designed by professional photography.
digital camera
D digital camera is also called digital camera. The full English name is Digital Camera, referred to as DC. Digital cameras are products that integrate optical, machinery, and electronic integration. It integrates the conversion, storage and transmission of image information, has the characteristics of digital access mode, interacting with computer and real -time shooting. Digital cameras first appeared in the United States. More than 20 years ago, the United States used it to send photos to the ground through satellites. Later, digital photography turned into civilian use and continued to expand its application scope.
The development of the development process of the digital camera
2005.07.28 11:27:08
It has been developing for nearly 200 years. In these 200 years, the camera has gone through black and white to color, evolved from pure optical and mechanical architecture to optical, mechanical, and electronics. From traditional silver salt film to today's digital memory as a record medium. Looking at the clouds and seeing the clouds, the emergence of digital cameras officially marked the leap -forward development of the camera industry towards the new era of digitalization, and people's image life has also changed completely.

Although it is "what you see is the income", because when taking pictures in the sun, unless you shoot backlight, the shooting object is generally the sun, so the screen is also under the sun, and basically nothing can be seen. If there are people who use the camera, if they are over 40 years old, because the eyes are beginning to be old flowers, the results can not be seen without wearing a flower mirror.
It's zoom multiple, zoom multiple, mainly determine the longest focal length, such as 12 times zoom, the longest focal length reaches 420 mm, so that the long -distance camera function is very strong, can shoot long -view, birds, beasts, beauty, etc. Wait. You can get a large sun and moon when shooting the sun and the moon.
has no above functions, which has a great impact. There is no good viewfinder, and the success rate of taking photos is greatly reduced. If the zoom multiple is small, you cannot shoot the scenery from a distance. For example, if you want to shoot a beauty, the other party finds that people will look at you, or flatten you directly. At least you get a unnatural expression, and you cannot shoot wild animals. You are close to the birds. Just fly. If it is just a photo of "One Tour", it is not important to have any.
The viewfinder
The viewfinder is to monitor the image part of the image through the eyepiece on the digital camera. The current mirror of the digital camera is only black and white viewer and color viewfinder. But for professional -level digital cameras, it is a black and white landscape, because black and white landscapes are more beneficial to photographers to correctly compose. The digital camera is the same as its liquid crystal display structure. Both use TFT LCD, and the difference is that the size of the two and power consumption.
The general digital camera's viewfinder is relatively small, only enough to close one eye to observe; for some professional models, or some shoulder bracket DVs, its pixels are even better than LCD screens. To be big, this is convenient for the photographer to see the shooting screen.
Compared with its LCD display, the viewfinder has another advantage, that is, power saving. Generally speaking, when the LCD display is turned off, only the viewfinder can be used, which can save at least four points. The power of one time.
The viewer of the digital camera can generally rotate in the vertical direction. There are even 90 degrees of rotation angle, which is more convenient for photographers to shoot while standing in a standing posture. Moreover, most of the viewfinder can change the distance of the eyepiece, which is convenient for photographers with myopia to wear glasses.
In general, for professional photography, the viewfinder is still very important, so we look at those professional DVs, which are very good in the manufacturer of the viewfinder. This is for convenience Designed by professional photography.
digital camera
D digital camera is also called digital camera. The full English name is Digital Camera, referred to as DC. Digital cameras are products that integrate optical, machinery, and electronic integration. It integrates the conversion, storage and transmission of image information, has the characteristics of digital access mode, interacting with computer and real -time shooting. Digital cameras first appeared in the United States. More than 20 years ago, the United States used it to send photos to the ground through satellites. Later, digital photography turned into civilian use and continued to expand its application scope.
The development of the development process of the digital camera
2005.07.28 11:27:08
It has been developing for nearly 200 years. In these 200 years, the camera has gone through black and white to color, evolved from pure optical and mechanical architecture to optical, mechanical, and electronics. From traditional silver salt film to today's digital memory as a record medium. Looking at the clouds and seeing the clouds, the emergence of digital cameras officially marked the leap -forward development of the camera industry towards the new era of digitalization, and people's image life has also changed completely.
In October 17, 1969, Ball and Smith at the Bell Institute in the United States have announced the invention of "CCD" (charge coupling element). Get widely used. The latest improved editions such as 4 -color CCD, Super CCD, etc. have continued to emerge. Pixels have already spans 10 million pixels, but the imaging effect has also become perfect.
. After more than ten years of continuous development, the DC industry has already gone out of its own child, the design is more mature, the operating function is growing, and with the further reduction of manufacturing costs, the development of such products is developed. It has been revealed that unlimited development signs have been revealed.
In general, the development process of the DC industry for more than ten years has always adhered to the development context of "higher, faster, stronger, and more humane". In today's digital camera market, it will become so prosperous and beautiful. While enjoying the convenience brought by technology, people still can't help but read the bumpy roads that have been traveled at the beginning of the birth of a digital camera. Some classic models that have a significant impact on this industry are still unforgettable.
This-life explosion
The lives suddenly appeared in the Cambrian, and the entire earth became colorful and full of life. Archeologists The reason for its reason has not been given a clear answer. In the 1980s, it was tantamount to the Cambrian of the digital camera industry. In less than ten years, the digital camera quickly broke away from 襁褓 and gradually learned to stagnate. Although the resolution was still very low at that time, the participation of many manufacturers participated Make this industry full of vitality.
Mabika —— the world's first electronic camera that does not need to be sensitive film
November 1973, Sony officially started the research of "electronic eyes" CCD research On the basis of continuous technical accumulation, it launched the world's first electronic camera in the world in 1981, the static video "MABIKA". The camera uses a CCD thin piece of 10 mm × 12 mm with a resolution of only 570 × 490 (279,000) pixels. For the first time, the light signal is changed to electronic signal transmission.
followed closely, and Company Panasonic, Copal, Fuji, Canon, Nikon and other companies also started the development of electronic cameras. From 1984-1986, their own prototype electronic cameras were launched. The outbreak started.
Sony MYC-A7AF —— The first time the digital camera has a pure physical operation method
Sony's hand, it can be seen that the company's market position today is by no means a "virtual name". In 1986, Sony released MyC-A7AF. For the first time, the digital camera had a pure physical operation method. It could record static images on 2-inch plates. Pixel resolution has also expanded to 38 million pixels. Casio VS-101 —— The first CMOS photosensitive device electronic camera
In 1987, Casio first released the VS-101 electronic camera with CMOS photosensitive device on the market, although the resolution can only reach 28 million pixels, , But this is of great significance to the DC industry.
It today, the competition for the orthodox aspects of CMOS and CCDs in digital camera sensor has been settled. In addition to being widely used on the Canon high -end camera today, CMOS has been widely used. CCD regards CCD as the dominant direction of its own products. It is not necessary to deny that the advantages of CMOS have the advantages of full -scale, low energy consumption, etc., but the disadvantages of low dynamic scope cannot not help people "stay away".
The RC-760 ----- The first 600,000 pixel model
wants to obtain the shooting effect close to traditional cameras, improve the CCD pixel resolution counted as calculated The most fundamental solution, but in the early stage of the birth of a digital camera, it is easy to talk about it on the pixel. For a few years, manufacturers have been hovering at a level of 300,000 pixels. It was not until 1988 that Canon launched a 600,000-pixel model RC-760.
The electronic camera uses a 2/3 inch 600 million pixel CCD. The appearance is slightly rigid today, but this is the highest pixel machine at that time. The price is higher than today. It's expensive.
This-dinosaurs are fierce
In long evolution and evolution, life finally gave birth to a more advanced form of life, and the world suddenly became more lively. Woke up. The continuous accumulation of technology in the 1980s finally ushered in the true prosperity of the digital camera industry in the 1990s. Since then, digital cameras have established their basic survival model.
Kodak DCS 100 —— The general mode of digital camera in the world
In 1990, Kodak launched the DCS100 electronic camera, which was the first time in the world to establish a digital camera in the world. General model, since then, this model has become the industry standard.
For professional photographers, if a new machine has their familiar body and control mode, it will undoubtedly become simpler. In order to cater to this consumer psychology, Kodak Company applied to the DCS100 in the well -known Nikon F3 fuselage at the time. Internal functions have made great changes except for focusing screens and roll motors. Nikon lens is really detailed.
The digital SLR uses a 20.5 x 16.4mm CCD with 1.4 million pixels, and the light change multiple is 1.8X. The external storage unit (DSU) is used. DSU is similar to today's camera base. Battery uses battery as a driver energy. The built -in 200MB memory can store 150 unprepared RAW photos.
The view mode is also very primitive compared to today's machine. The photographer can use the optical viewfinder on the camera or the 4 -inch LCD LCD screen on the DSU. But very high -end. The price of this machine at that time was equivalent to 225,000 yuan today, which is really expensive.
In DCS100 was successful, Kodak launched the DCS100 subsequent model DCS200 in 1992. It finally got rid of DSU's burden, and the memory was placed inside the fuselage. The shooting becomes very comfortable.
Neon/Fuji E2/E2S —— The digital SLR
does not matter whether Kodak or Canon, the original tradition was used in the early product design Although the camera's film fuselage, although this can make professional photographers feel the affinity of the product, the product is inevitable to make people feel boring. In 1995, the two giants of Nikon and Fuji joined forces to launch a newly designed E2/E2S. It no longer copied the traditional fuselage of old teeth and adopted an integrated design style, which can easily make people feel refreshing.
The resolution of this digital SLR is only 1.3 million pixels. Compared with the 6 million pixels of the Kodak DCS460 of the same age, it is very different. The most special feature of E2/E2S is that Nikon's newly developed ROS optical system is adopted. Through a set of optical components, the light is projected to the CCD with an area of less than 35mm. The aperture has been severely shrinking, and the quality of imaging has been greatly affected.
The integrated design makes the appearance of this machine look more concise, but the complexity of the internal structure inevitably causes the appearance of the appearance volume, and the total weight also shows signs of out of control. This machine has accumulated a lot of experience for Nikon's digital SLR research and development. After four years of listing, Nikon launched an epoch -making D1, and the Baiji period of the digital camera industry was completely over.
S Jurassic-dangerous jungle
The biological category of Jurassic is already very complete. There is also a very fierce Bawang Dragon. Each animal seems to be more powerful to survive in this world. Only in this way can you be easy to spend in this weak meat and strong jungle.
INkon D1 —— Nikon's first self-developed digital SLR
In June 1999, Nikon finally launched the company's first digital SLR-D1 developed by the company. The price of the Kodak DCS series cameras has launched a new era of digital SLR people.
The body used in this digital SLR is completed by the traditional camera F5, which still maintains a very attractive professional temperament. It has a built-in 2.74 million pixel CCD and ISO's sensitivity is 200-1600. It uses CF card/IBM micro-hard disk as a storage medium. The supported file formats include three types: JPEG, TIFF, and RAW. Essence
In Canon EOS 1D — Canon's digital single hair myth
For a long time, while the pixel resolution competes, the competition of manufacturers in shooting speed is also in full swing. In order to completely surpass the myth created by Nikon D1, Canon launched the EOS 1D dedicated to fast shooting in September 2001, thus overwhelming the Nikon D1 in speed and technical indicators, and achieved a new generation of legends in the DC industry.
The digital SLR has a 4-megapixel resolution, ISO sensitivity is 100-1600, and CF card/IBM microcracks are also used as a storage medium, which is priced at about $ 7,000.
Olympic Bas E-1 —— 4/3 system masterpieces
, just like early notebook manufacturers, in order to create the greatest trouble for the opponent, digital SLR When designing product design, manufacturers must deliberately avoid compatibility with their opponents. In this way, any brand of digital camera components cannot be universal. After the component is damaged, users can only buy product replacement of the same brand. The profit was maximized.
The notebooks today have long been mutually compatible. This can be said to be the increasingly enlightened performance of computer manufacturers, but the change of the digital camera industry is also quietly carried out. In December 2003, Olympus released the E-1 of the "4/3 system" jointly developed by the two companies of Kodak and Fuji.
4/3 system specifies the area of the CCD photosensitive device, the distance between the CCD and the lens, and the diameter of the lens. This is definitely unimaginable in previous products.
e-1 uses a 5-megapixel CCD, the ISO sensitivity range is 100-800, using the CF card as a storage medium, supporting JPEG, RAW, and TIFF file format. At the beginning of the release, the price was as high as 16,000 yuan.
Tun EOS 300D -a generation of civilian Digital SLR King
The digital SLR function is powerful and the picture quality is beautiful, but the high price is that it cannot approach civilians The biggest obstacles of the people. In order to successfully complete the popularity of digital SLR, manufacturers are always digging to find ways to reduce costs. It is with their unremitting efforts that a group of reasonable civilian digital SLR has finally emerged, and the Canon E0S 300D It is undoubtedly a pioneer of this process.
In August 2003, Canon launched an EOS 300D with a plastic body, which integrates the predecessor's EOS-10D CMOS photosensitive device. The original competition pattern of the market.
This camera uses 6.3 million pixels CCD, ISO sensitivity is 100-1600, and CF cards are used as a storage medium. The design applies the three colors of silver, gray, and black, and the overall feeling is pretty good.
2006.5.30 Supplement:
The digital camera is the same as the traditional camera, both in appearance or function. Essence The most obvious difference between the digital camera and the traditional camera is on the storage medium. The digital camera uses disk pads or memory cards that can be recorded to access images. After shooting The online method is transmitted to the computer for processing, and it can also be printed directly from a printer with special functions. The biggest advantage is that when the shooting effect is not satisfactory, you can delete and re -shoot in time. At the same time Generally, you can buy negatives, which can save negative costs and save printed fees at the same time. In terms of processing efficiency, digital cameras have a very large advantage over traditional cameras. Hundreds of photos taken in the past event, if you use traditional cameras, you must wait for the time of rinse and mail, but now, but now As long as the digital camera is passed to the computer through the digital camera, and the email mails can be used to mail it to the participants in real time. Therefore, in this era of efficiency in this thing, it can be said that it is a very convenient image device. one.
The viewfinder is used for viewing, and taking pictures always have to be viewed. The common is synchronous viewing, beam axis, and screen views.
The synchronous scene, the small screen is consistent as the large screen. With the adjustment of various aspects, such as exposure, focusing, etc., what you see also changes simultaneously. "". In this way, you can't see anything without turning on. It is the most convenient and power -saving to use this viewfinder.
Thexicated by the horizons, you can see things without turning, but the errors and income are usually small composition, the composition is large, the difference is larger, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus, and the focus. Manual adjustment of exposure and so on cannot be obtained intuitively. You have to know what results are taken after shooting.
The without the scene, everything depends on the screen, Lenovo S500 is this design. Although it is "what you see is the income", because when taking pictures in the sun, unless you shoot backlight, the shooting object is generally the sun, so the screen is also under the sun, and basically nothing can be seen.

At least you get a unnatural expression, and you cannot shoot wild animals. You are close to the birds. Just fly. If it is just a photo of "One Tour", it is not important to have any.
The viewfinder has at least two benefits. You can shoot more power saving without opening the display screen (at least for those who are used to the viewfinder. Monitor the image through the viewfinder, the current eyepiece of the digital camera is only black and white landscape and color viewfinder. Correct composition. The digital camera's landscape structure is the same as its LCD display. Both use TFT LCD, and the difference is that the size of the two and the power consumption. Small, only enough users to close one eye observation; for some professional models, or some shoulder -type DV, its pixels are even larger than LCD screens, which is convenient for the photographer to see the shooting screen.

Compared with its LCD display, the viewfinder has another advantage, that is, power saving. Generally speaking, when the LCD display is turned off, only the viewfinder can be used. For a while,
The viewfinder of the digital camera can generally rotate in the vertical direction. There are even 90 degrees of rotation angle, which is more convenient for photographers to shoot when standing in a standing posture. Moreover, most of them, most of the ones The viewfinder can change the distance of the eyepiece, which is convenient for photographers with myopia wearing glasses.
In general, for professional photography, the viewfinder is still very important, so we look at those professional ones DV, the manufacturer of the viewfinder is very good. This is designed to facilitate professional photography.
