History of digital photography – the scanner:

Back to the history of digital photography rather than the history of the moving image. The next significant step would be the development of image scanners.

These didn’t actually take photographs, but they did copy an image already created.

In 1957 a “drum scanner” was developed by Russell Kirsch. The scanner picked up the different intensities of light and shade in a picture. It saved them as a binary, i.e. digital, signal.

NB: Photocopiers stem from the development of this technology. The first one was made by Xerox in 1959. A huge thing, slow and expensive. But remarkably popular nonetheless. Up, up and away!
