Camera. – P. D. Brewster, an American inventor, who was one of the first to apply the bipack system to colour cinematography, has a number of patents to his credit covering various cameras and ...
Unlike other additive systems invented in previous years, Gualtierotti tried to avoid the phenomenon of chromatic aberration inherent in the use of multiple lenses or the creation of successive separation records. The proposed solution was based on ...

Additive 3 color: Lenticular screen
The basic idea of the lenticular film was developed by the German Raphaël Liesegang in 1896 and applied to still photography by the French Rodolphe Berthon in 1908.
The lenticular process applies tiny cylindrical lenses embossed on the film support ...

Subtractive 2, 3 or 4 color: Beam-splitter and bi-pack, later dye-transfer
The Roncarolo system required a camera capable of recording two panchromatic negatives (which became three or four in subsequent patents) through the use of a beam splitter and red and green filters.
The chromatic information registered on the two or ...
Three matrices in the subtractive primary colors are printed on the gelatin of the final print. Supposedly, the used dyes were particularly fast and able to prevent color bleeding. Pokorny started working on color cinematography in the 1920s, often ...
