摘要： A photographic film, particularly a 35-mm film, which can tear only in a direction opposite from the picture regions of the film. Cuts, such as a V-shaped notch or a linear cut, are formed in the film extending from each perforation in a direction opposite to the picture region of the film. If a high force is applied to the perforations of the film while the film is being conveyed, the film will tear only at the notch thus absorbing the force and preventing damage to the film conveying mechanism.
