ABSTRACT:
Photographic film comprises a flexible substrate sheet divided on one side into a multiplicity of different picture areas provided with respective layers of photosensitive chemical material having a plurality of different photosensitivities. Thus, each sheet or strip of film is essentially multiple ASA film. Such a film strip is provided with detectible code on a substrate sheet for encoding the photosensitivities of the different picture areas in a readable format. A camera utilizing the film is provided with a magnetic reader for determining film speeds or photosensitivities of the different picture areas on the film. A film transport mechanism is controlled by a microprocessor to move an unexposed picture area of an appropriate ASA to an exposure zone of the camera, either in response to a manually selected ASA or an automatic determination of optimal film speed in accordance with lighting conditions as detected by a light sensor, subject distance, etc. The microprocessor includes a memory for storing in encoded form which picture areas of the film have been exposed.
