ABSTRACT:
A photographic camera enables pseudo telephoto and pseudo panoramic prints to be produced from exposed film frames by coding the film frame to identify the selected pseudo format. In the camera, a manually operated member is movable to a position corresponding to the actual field of view of the objective lens and to respective positions corresponding to pseudo telephoto or pseudo panoramic fields of view reduced from the actual field of view. Code means, responsive to movement of the manually operated member to a position corresponding to a pseudo telephoto or pseudo panoramic field of view, encodes a film frame with indicia representative of the selected pseudo field of view to identify the portion of the film frame covered by the pseudo field of view. The identified portion of the film frame can then be enlarged to produce a pseudo telephoto or pseudo panoramic print.
A photosensitive element in the exposure control system of the camera provides a measure of the brightness of light reflected from a subject to be photographed. Light control means, responsive to movement of the manually operated member to a position corresponding to a pseudo telephoto or pseudo panoramic field of view, controls the amount of light reaching the photosensitive element in accordance with the amount of light available to the selected pseudo field of view. Thus the portion of the film frame used to produce the pseudo telephoto or pseudo panoramic print can be more accurately exposed.
