ABSTRACT:
A photographic camera successively exposes a photographic film in different frame sizes, so that the processed photographic film exposed with those different frame sizes can be automatically printed. The camera varies the length and width of an exposure opening in the camera body in the film-feed direction and film width direction. The photographic camera magnetically or optically records an exposure opening signal indicative of the size of the exposure opening on the photographic film.
