ABSTRACT:
A photographic film is provided with bar codes indicating frame numbers attached to respective frames of the photographic film and a specific bar code indicating a specific part thereof. The specific bar code is located before or after the specific part of the photographic film. Each frame number bar code is read to determine the decimal frame number of each frame of the photographic film. If the bar code attached to the last frame is not read, it is determined that the bar code not read indicates a frame number for the last frame by reading the specific bar code before or after the fault in reading the bar code of the last frame.
