ABSTRACT:
A camera uses an organic thin film of electroluminescent material to expose photographic film, in predetermined positions outside scene frames, to patches of light in three complementary colors, either additive or subtractive. According to one feature, the patches are exposed in predetermined locations interspersed with film perforations or located in a known relationship with the exposed frames, permitting a printer to establish the orientation of film relative to the camera during the exposure. The patches also confirm that a picture was taken.
