A photographic camera (10) includes a film supply chamber (14); a film takeup chamber (16) and a film exposure gate (18) positioned between the chambers. The gate defines a maximum exposed image width (W) in a direction of film travel between the chambers and a maximum exposed image height (H) in a direction transverse to the direction of film travel. A plurality of mask members (24, 26) extend transverse to the direction of travel, each mask member being configured for masking only a portion of the maximum exposed image width. There is no mask in the camera configured for masking a portion of the maximum exposed image height. A mechanism (88-94) moves the mask members toward or away from a center of the exposure gate to reduce or increase only a final exposed image width (W.sub.e), without masking the maximum exposed image height. As a result, the final width of the exposed image indicates a required enlargement of exposed image to produce a pseudo telephoto print. A viewfinder (22) may have mask members (28-34) which move synchronously with the mask members at the exposure gate; or with a zoom lens element (110-114) which also moves synchronously with the mask members at the exposure gate.
