ABSTRACT:
A lens-fitted photographic film package for steroscopic photography, wherein a plurality of images of the same subject are taken simultaneously through a corresponding number of taking lenses disposed horizontally side by side at a given distance from each other. Behind the respective taking lenses, exposure chambers and exposure frames for defining the respective exposure areas on the film surface are formed. The exposure frames are each gently curved, and a guide surface for supporting the rear surface of the film is curved complementarily to the exposure frames. Pressing members formed in the guide surface press the film against the end surfaces of walls separating the exposure frames, so as to curve the film along the exposure frames. The film is thus wavy, with forwardly concave film portions in the exposure frames alternating with rearwardly concave film portions between the exposure frames. The optical axes of the taking lenses are upwardly or downwardly offset from the center of the film surface, so that the space under or over the exposure frames can be utilized efficiently.
