Another Little Lesson


After posting the history on film photography I though it would be interesting to do some research about digital photography and this is what I found:

Digital camera technology is directly related to and has evolved from the same technology that recorded television images. In 1951, the first video tape recorder (VTR) captured live images from television cameras by converting the information into electrical impulses (digital) and saving the information onto magnetic tape.
Although the consumer digital camera was not invented until the late 90's, digital images were being used in government work. During the 1960s, NASA converted from using analog to digital signals with their space probes to map the surface of the moon (sending digital images back to earth). Digital imaging also had another government use at the time that being spy satellites. Beginning in the mid 1970's, Kodak has invented several solid-state image sensors that are able to convert light to digital picutures for professional and consumer use. In 1986, Kodak scientists invented the world's first megapixel sensor, which was capable of recording 1.4 million pixels that could produce a 5x7-inch digital photo-quality print. In 1987, Kodak released seven products for recording, storing, manipulating, transmitting and printing electronic still video images. The first digital cameras for the consumer-level market that worked with a home computer via a serial cable were the Apple QuickTake 100 camera (1994) and the Kodak DC40 camera (1995).

And that's history!
