A Brief History of Photography
took the first ever photo of a person in 1838 when, (know as a daguerreotype produced on a copper plate) in
a Paris street, a pedestrian stopped for a shoe shine, long enough to be
captured by the long exposure of several minutes. Meanwhile, William Henry Fox
Talbot (11th February 1800 - 17th September 1877) a British inventor, had
earlier discovered another means to fix a silver process image but had kept it
secret. After reading about Daguerre's invention, Talbot refined his process so
that portraits were made readily available to the masses. By 1840, Talbot had
invented the calotype process, which creates negative images. Talbot's famous
1835 print of the Oriel window in Lacock Abbey, Wiltshire is the oldest known negative in existence. Today Lacock Abbey is the home of The Fox Talbot Museum.
The first recorded attempt at building a digital camera was in 1975 by Steven Sasson, an engineer at Eastman Kodak. It used the then-new solid-state CCD image sensor chips developed by Fairchild Semiconductor in 1973.The camera weighed 8 pounds (3.6 kg), recorded black and white images to a cassette tape, had a resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds to capture its first image in December 1975. The prototype camera was a technical exercise, not intended for production.
