Abstract

Abstract A photographic camera capable of taking various size exposures comprises a back frame opening for making a full size exposure on a film in the camera, and respective masking blades supported for pivotal movement between a masking position for masking corresponding portions of the back frame opening to allow only a reduced size exposure to be made on the film and a non-masking position not masking the corresponding portions of the back frame opening to allow a full size exposure to be made on the film. The masking blades are connected via a connecting link having at least one elastic portion which constitutes a living hinge to permit the masking blades to be pivoted between their masking and non-masking positions. Preferably, the masking blades and the connecting link are integral to be one-piece.
