ABSTRACT:
A photographic film which makes it easy to recognize the positions for cutting the photographic film into frames and which can be used for both stereoscopic cameras and general cameras. The photographic film 1 is perforated as designated at 2 along near both the upper and lower side edges thereof maintaining a pitch which is one-half the pitch P of the pair of right and left exposure surfaces of a stereoscopic camera. The perforated holes 2 are located in a gap among the frames irrespective of whether pictures are taken by using a stereoscopic camera having a film-feeding mechanism that corresponds to the perforated holes 2 of the photographic film 1 or by using a one-frame shooting camera. The photographic film 1 can be cut maintaining a correct frame size when it is cut relying upon the upper and lower holes 2 as marks.
