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.
People started experimenting with color photography in the 1840s. Within about 10 years, Levi Hill had worked out a complicated process, with other, more successful processes following. A big shift occurred in 1935, when Kodak brought out Kodachrome, initially as a 16mm color film for home movies (slide film followed). The following year, Agfa brought out Agfacolor Neu, which improved on Kodachrome with a dye coupler technique. Color film and processing were expensive, though, so it took another couple of decades of development to make color photography common at the consumer end of the market.
