ABSTRACT:
A photographic camera capable of taking interspersed full size and panoramic size exposures comprises a rectangular back frame opening for forming a full size exposure on a film in the camera, and respective masking blades supported for pivotal movement to a masking position for masking an upper rectangular portion and a lower rectangular portion of the back frame opening to allow only a panoramic size exposure to be formed on the film and to a non-masking position not masking the upper and lower portions to preclude a panoramic size exposure from being formed on the film. According to the invention, the masking blades have respective extension means at which they are supported for pivotal movement for moving the masking blades in only one direction from their non-masking position to their masking position and to return the masking blades in only one direction, different than the first-mentioned direction, to their non-masking position.
