Abstract
A photographic camera apparatus with electronic image enhancement operates to control the exposure of a photosensitive material to scene light received directly from a scene to be photographed in a manner whereby the photosensitive material is exposed to an extent less than a selected optimum exposure value and the scene light is simultaneously electronically sensed to provide electrical signal information corresponding thereto to control an additional electronic exposure of the photosensitive material so that in conjunction with the direct exposure to scene light there is substantially provided the selected optimum exposure value.
