Abstract
In a camera, one of a plurality of predetermined print aspect ratios is selected for each scene by manual operation of a print mode selection switch, and mechanically readable data representing the print aspect ratio is thereby recorded on the photographic film for each original frame during photographing. The original frames are recorded at a constant taking aspect ratio in the same size on the photographic film. During printing, the trimming data is read from the photographic film, and a part of the original frame that excludes both lateral sides of the original frame is printed based on the trimming data, so as to make a photographic print having the selected print aspect ratio. The camera is provided with a device for changing the field of view, that cooperates with the print mode selection switch, so as to change the aspect ratio of the field of view in accordance with the selected aspect ratio. The photographic film has been previously recorded with several pairs of marks, each pair indicating lateral side border lines of a trimming range which corresponds to one of the predetermined selectable print aspect ratios. A visible mark corresponding to one of the previously recorde…
