ABSTRACT:
In the disclosed photographic exposure control system, an exposure mechanism generates at least one controllable exposure parameter for regulating the exposure of a photosensitive material. A coding circuit is set to produce digital signals corresponding to at least one photographic value. A control device between the coding circuit and the exposure mechanism calculates the exposure parameter and controls the coding circuit. The coded values are then suitably displayed to the photographer.
