This is a list of color film processes known to have been created for photographing and exhibiting motion pictures in color since the first attempts were made in the late 1890s. It is limited to "natural color" processes, meaning processes in which the color is photographically recorded and reproduced rather than artificially added by hand ...
Freeze-drying causes less damage to the substance than other dehydration methods using higher temperatures. Nutrient factors that are sensitive to heat are lost less in the process as compared to the processes incorporating heat treatment for drying purposes. [2] Freeze-drying does not usually cause shrinkage or toughening of the material being ...
Excerpt from the surviving fragment of With Our King and Queen Through India (1912), the first feature-length film in natural colour, filmed in Kinemacolor. This is a list of early feature-length colour films (including primarily black-and-white films that have one or more color sequences) made up to about 1936, when the Technicolor three-strip process firmly established itself as the major ...
In color film, this backing is "rem-jet", a black-pigmented, non-gelatin layer which is removed in the developing process. [32] Eastman Kodak manufactures film in 54-inch (1,372 mm) wide rolls. These rolls are then slit into various sizes (70 mm, 65 mm, 35 mm, 16 mm) as needed.
It becomes the first commercially successful color photography product. 1908 – Kinemacolor, a two-color process known as the first commercial "natural color" system for movies, is introduced. 1909 – Kodak announces a 35 mm "safety" motion picture film on an acetate base as an alternative to the highly flammable nitrate base.

In 1940 he published his seminal book Photographing in Color, using high quality illustrations to explain his techniques. [19] Ferenc Berko, a classic photographer [vague] who lived during the rise of color film, was one of the photographers who immediately recognized the potential of color film. He saw it as a new way to frame the world; a way ...
Cellulose diacetate film was first created by the German chemists Arthur Eichengrün and Theodore Becker, who patented it under the name Cellit, from a process they devised in 1901 for the direct acetylation of cellulose at a low temperature to prevent its degradation, which permitted the degree of acetylation to be controlled, thereby avoiding total conversion to its triacetate.
Used commercially from 1909 to 1915, it was invented by George Albert Smith in 1906. [ 1 ] [ 2 ] It was a two-colour additive colour process, photographing a black-and-white film behind alternating red/orange and blue/green filters and projecting them through red and green filters. [ 3 ]
