Abstract
The system involves splitting the light spectrum from a color picture to be reduced in size into first and second spectral portions which are simultaneously photographed with black and white film. The black and white film can be reduced to an extremely small size for storage. Reproduction of the color picture is accomplished by projecting simultaneously from both black and white film images the respective light spectral portions and recombining them to produce the full color picture.
