One of the
early methods of taking
color photos was to use three
Each camera would have a
color filter in front of the lens. This technique provides the
photographer with the three basic channels required to recreate a color
image in a darkroom or processing plant. Russian photographer Sergei Mikhailovich Prokudin-Gorskii developed another technique, with three
color plates taken in quick succession.
Practical application of the technique was held back by the very limited
color response of early film; however, in the early 1900s, following the
work of photo-chemists such as H. W. Vogel, emulsions with adequate
sensitivity to green and red light at last became available.
The first color plate, Autochrome, invented by the French Lumière
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. In
1935, American Kodak introduced the first modern ('integrated tri-pack')
color film, Kodachrome, based on three colored emulsions. This was
followed in 1936 by Agfa's Agfacolor Neue.

Unlike the Kodachrome tri-pack
process the color couplers in Agfacolor Neue were integral with the
emulsion layers, which greatly simplified the film processing. Most modern
color films, except Kodachrome, are based on the Agfacolor Neue
technology. Instant color film was introduced by Polaroid in 1963.
