description	A photographic exposure control system incorporating a multizone shutter arrangement and a photoresponsive array, with each element of the array being responsive to one of a plurality of spacially oriented areas of the photographic scene and in control of one shutter zone which transmits image-carrying rays from that scene area to a pictorially corresponding area of the film to selectively compress the range of scene brightness to within the linear range of the film thereby enhancing shadow detail. In the illustrated embodiment, the exposure system in effect controls the multi-zone shutter to expose film areas corresponding to bright scene areas, having a relative brightness falling within the linear range of the film, at one exposure factor and film areas corresponding to darker scene areas at a greater exposure factor.
