Colour Photography
Color photography
was explored throughout the 1800s. Initial experiments
in color could not fix the
photograph and prevent
the color from fading. The first permanent color
photo was taken in 1861 by the physicist James
Clerk Maxwell. The first color film, Autochrome,
did not reach the market until 1907 and was based
on dyed dots of potato starch. The first modern
color film, Kodachrome, was introduced in 1935
based on three colored emulsions. Most modern
color films, except Kodachrome, are based on technology
developed for Agfacolor in 1936. Instant color
film was introduced by Polaroid in 1963.
One of the early methods of
taking color photos was to use three cameras.
Each camera would have a color filter in front
of the lens. This technique provides the photographer
with the three basic channels required to remake
a color image in a darkroom or doling out plant.
Color photography may form images
as a positive clearness, intended for use in a
slide projector or as color negatives, intended
for use in creating positive color enlargements
on specially coated paper. The latter is now the
most common form of film (non-digital) color photograpy,
owing to the introduction of automated photoprinting
equipment
