ABSTRACT:
Film encodement method and apparatus for optically encoding image frame format information on the film in a camera adapted to receive film having film metering perforations along one side of the film which are spaced apart by the length of film frame areas on the film. Data representing a desired frame format for the resultant photoprint is optically encoded on the film between the spaced apart perforations by the same perforation sensor LED, operative in the visible light spectral region, as is used to perform film metering in the camera.
