Almost all color imaging uses Maxwellâs principles to this day. When motion pictures were invented in the 1890s, there was once again a desire for color images. By 1900, the PathÃ© company in France had designed an elaborate system to hand-color film frames with the use of stencils.
There were many attempts during this time at capturing color photography, however, in 1861, physicist James Clerk Maxwell would create the world's first permanent color image. 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 recreate a color image in a darkroom or processing plant. The first color film, Autochrome, did not reach the market until 1907 and was based on dyed dots of potato starch.
