ABSTRACT:
A photographic camera enables pseudo telephoto and pseudo panoramic prints to be obtained from normal exposures coded to identify the selected type print. In the camera, an objective lens is adjustable to vary its angular field of view within a field range having a wide angle limit and a telephoto limit. A manually operated member is movable to a plurality of positions corresponding to respective fields of view within the field range of the lens, for adjusting the lens to a selected field of view. Also, the manually operated member is movable to other positions corresponding to respective pseudo telephoto or pseudo panoramic fields of view outside the field range of the lens, when the lens is adjusted to the telephoto limit or the wide angle limit. 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 an exposure taken with the lens at its wide angle or telephoto limit with indicia representative of the pseudo field of view. This enables the portion of the exposure covered by the pseudo field of view to be identified for enlargement printing to obtain a pseudo telephoto or pseudo panoramic print.
