ABSTRACT:
A multiple exposure-format camera comprises an exposure opening having an aspect ratio, and a flexible curtain-mask provided with a plurality of mask openings having respective aspect ratios that are different than the aspect ratio of the exposure opening. The curtain-mask is supported for movement from one storage chamber to another storage chamber to successively locate the mask openings at the exposure opening to change the aspect ratio for the exposure opening. At least one of the storage chambers is configured to receive a film container to store a portion of the curtain-mask about the film container. This allows the camera to be made relatively compact.
