#1. The First Photograph. The worldâs first photograph made in a camera was taken in 1826 by Joseph NicÃ©phore NiÃ©pce. The photograph was taken from the upstairâs windows of NiÃ©pceâs estate in the Burgundy region of France.
The first permanent color photograph was made in 1861 by James Clerk Maxwell. Earlier attempts resulted in color photographs whose colors faded rather quickly. ****************. The first color plate, Autochrome, invented by the French LumiÃ¨re brothers, reached the market in 1907. It was based on a 'screen-plate' filter made of dyed dots of potato starch, and was the only color film on the market until German Agfa introduced the similar Agfacolor in 1932.
