Keller-dorian cinematography
Encyclopedia
Keller-Dorian cinematography was French technique from the 1920s for filming movies
in color
. It used a lenticular
process to separate red
, green
and blue
colors and record them on a single frame of black-and-white film. This contrasts with other systems, for example Technicolor
, which divided the colors into more than one frame on one or more pieces of film.
The system was used to film several scenes of Abel Gance
's Napoléon (1927) and for La Femme et le Pantin by Jacques de Baroncelli
(1928). However, projection
of this process in movie theater
s seems to have been more difficult, so neither of these films was ever presented using this technique. Also, making prints
was described by one source as "impossible."
This process was used by Kodak for Kodacolor
, introduced in 1928 as the first amateur filmmaker's 16mm film color process available for the home movie
market.

Red
Red is any of a number of similar colors evoked by light consisting predominantly of the longest wavelengths of light discernible by the human eye, in the wavelength range of roughly 630–740 nm. Longer wavelengths than this are called infrared , and cannot be seen by the naked eye...

Green
Green is a color, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of roughly 520–570 nanometres. In the subtractive color system, it is not a primary color, but is created out of a mixture of yellow and blue, or yellow and cyan; it is considered...

Blue
Blue is a colour, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of roughly 440–490 nm. It is considered one of the additive primary colours. On the HSV Colour Wheel, the complement of blue is yellow; that is, a colour corresponding to an equal...
