The first digital canon mv750i battery single lens reflex camera (DSLR) as early as the early 90s in the 20th century has been available, but not until 2000 that the camera began to widely proliferate. Work only a few short years, digital SLR users have been relatively few photographers news and public relations to the majority of the development of professional photographers and amateur photographers. This huge leap on the one hand due to sensor design and digital storage of significant progress, since the main camera on the other hand is the fierce competition among manufacturers, making the camera specifications rising costs continued to decline.
Until recently, trying to film to digital photography who also face the question: When will purchase the largest investment the minimum income? Rapid technological progress, the previous week's top high-end camera to become obsolete in the next week, nobody cares. But how much this situation has now eased; presented with progressive advances in technology, rather than revolutionary, the magnitude of price cuts has slowed. Technology is mature, all forms of digital photography - especially digital SLR photography - ushered in the first spring, people began to be widely accepted and loved.canon nb-2l battery
The dawn of the digital age
The late 20th century, 80, appeared in the first scanner, image processing software and the ability to take these powerful computers, the digital photography era began. At the time, is still photos taken with film, and then through a scanner to do digital processing. The computer equipment was extremely expensive (by today's standards look very low-level), thus the early use of the equipment of almost all the world's top newspapers. News publishers on the one hand in the endless competition with each other, trying to grab the opponent in front of sensational posted on the front page news, but also do everything possible to make the production system have been eliminated to achieve modernization. In fact, when they have begun writing for the computer design and layout, so no matter how high the cost, they use the computer sooner or later, armed with this aspect of photography.
Almost at the same time, digital capture images - that is, take a picture with a digital camera - start coming into view. At first, this film is very clumsy way. Early digital cameras can not handle the image and thus have been connected to the computer. To obtain color images, the need for exposure of the same picture three times, respectively - on the red, green and blue of the exposure time. In this way, shooting moving objects has become unnatural, but also means the camera when taking pictures must be firmly fixed, to ensure that the exposure between the two can not have the slightest move. This camera is severely limited by the use of only applies to studio still life photography.canon bp-308b battery
Digital SLR debut
These problems are resolved early, first of all, thanks to a single exposure to the three primary colors by capturing all of the new camera. Then appeared not connected to the computer models. In 1991 the first digital SLR camera marks the birth of a huge improvement. Developed by the Kodak camera, code-named DCS (later renamed the DCS100), is the world's first truly portable digital photography equipment. It is based on Nikon F3 body and the design and development, with universal Nikon lens is 35mm photographic camera people already familiar with, but less negative position, replaced by a digital sensor and a number of related electronic components.canon bp-608a battery
The device has numerous drawbacks inevitable. The camera can not store images, image transfer to go through the connection to the digital storage unit (DSU) to go, and photographers who like the same back carrying a heavy backpack digital storage unit. Second, the size of the sensor than a 35mm film to be small, so not all cover the lens field of view, the resulting focal length conversion factor of a say (now many digital SLR still the problem.) Another point, the image resolution for power and dynamic range (shadow and highlight areas of the resolving power) is also far better than the film can play a level, the sensor can be only 130 million pixel images - much better than the current mobile phone with camera pixel is even lower.
After several years, Kodak has introduced a number of consecutive new digital SLR, the DCS100 steadily with development. Most of these models using the Nikon body, there are some from the development based on Canon body. Technical content has slowly improved, but prices are still astronomical, high, according to models of different prices in 10000-25000 pounds (17000-42500 dollars) between the float.
Newspapers and news agencies played a pioneering role once again. Magazine photo paper printing photo quality demanding, and printed in the newspaper some of the standard will be relaxed. Newspapers, the transmission speed is critical draft, so the phasing out of the DCS series of cameras with longer time-consuming, to obtain images by scanning the negatives for the newspaper republication of the old method. Still later, a photo shoot after a few minutes with a laptop can be reached by e-mail before editing, digital SLR photography has finally received the news supremacy.
In 1999, Kodak and Nikon the two companies parted ways, digital technology accelerated the pace of progress. Nikon will soon be announced that it is developing its first digital SLR D1, the price of any one of the Bike Da are much cheaper. Fujitsu followed suit with its cheaper Finepix S1. 2001, the Canon D30 carrying join the fray.
Since then, there have been new digital SLR market, prices dropped lower and lower, configuration, continuous improvement. Computer is essential to any extension of a digital SLR since 2000, the computer's processing power and memory configuration has a leap forward, pushed the technology of digital photography to mature, and easy to use. Kodak - the great pioneer of digital photography - has been left in this race to the back in the end sadly retired in 2005.
A brief history of digital SLRs
1991, Kodak launched the world's first digital SLR DCS100.
Then in 1992, Kodak launched DCS200, which is the world's first with built-in image memory (a miniature hard drive) of the camera.
1994-1995 developed DCS420 and Kodak DCS460, made in the design of major improvements.
Kodak 1995, ushered in the first batch of competitors: the Nikon and Fuji teamed up to launch the FujixDS-515, and Minolta RD-175.
1998 Kodak DCS camera the other three asked the city: 520,560 and 315. Prior to this, DCS series cameras all designed based on the Nikon body, while the 520 and 560 for the first time using a Canon body.
During the 1998 World Cup proved a news photographer dominance of digital photography continues to strengthen its advantage in the constantly expanding.
Nikon 1999, Kodak released the fuselage with DCS620.
1999, Kodak and Nikon collaboration rupture; Nikon developed its own digital SLR Nikon D1, Kodak DCS series of prices is equivalent to a small part of the camera.
2000 Sydney Olympic Games, once again proved its digital SLR photography and news photography in the field of sports dominance.
In 2001 Canon introduced the first digital SLR (D30); Nikon broadens the product range; Kodak DCS760 into the market.
In 2002 Kodak introduced DCS Pro 14n, known as the world's first full-frame sensor with a digital SLR. However, the camera did not meet the standard of pre-publicity, followed discredited.
2001-2005, the main camera manufacturers have released a new digital SLR, the price plummeted, technical content rapidly.
Kodak 2005, tragically lost in the competition, announced the launch of the digital SLR market.canon bp-412 battery
