Digital photography is a new concept, but the technology used is not a new one. With different innovations and technological advancements over the years, photography as a hobby has become accessible to all. If you trace back, the history of digital photography dates back to as old as the 1950s. Events like the cold war have witnessed it during the early days. However, the significant development in digital photography took place with the popularity of television.
The videotape, first used to record television programs, was used in 1952. Before that time, the TV programs were either live or broadcast movies. The video tape-recorded an image that is not an actual image, but a coded signal. After that, those coded signals were run into a decoding machine where they are converted into pictures.
The invention of television proved to be a significant step in the popularity of digital photography.
The Importance Of Scanner In The History Of Digital Photography
The invention of the scanner was another milestone in the development of digital photography. Scanners did not really take photos, but copy the already created image. In the year 1957, Russell Kirsch developed a “drum scanner.” The scanner had the capability of picking up different light and shade intensities in a picture. It was afterward saved as a binary or digital signal.
The Role Of Space Race
Like the television and the scanner, the space race also has a role to play in the history of digital photography. During the year 1957, an American scientist named Von Braun and a Russian scientist named Sergei Korolev tried launching a satellite into space. It was the Russian scientist who was successful in launching the “Sputnik” satellite in October 1957. The following challenge was to land a man into space in the year 1960. But what is the importance of digital photography in both these events?
It was the era of the cold war, and the politicians on both sides were all aware of the fact that the satellite could carry a camera into space. The camera used to spy on the enemy. But the problem was that film developer was not available in space. Hence, mere taking pictures was of no use unless the satellite is received back to earth. Therefore, the need for a different system was there that had no films.
Digital cameras were the perfect solution here. They could not only take photos but also send them to earth through digital signals. Those signals were then decoded can be viewed. This proved to be a significant development in the history of digital photography.
Digital Photography On Earth
With the advent of digital photography in space, it was worked upon earth too. In the year 1973, an engineer called Steven Sasson made use of a CCD while working for Kodak.
The camera was a hefty one at that time. Therefore it was not preferred by consumers much. It was more of an experimental camera in the making. The need for modification was much felt and eventually led to the development of modern digital cameras.
