Abstract
A film is described which has circular perforations in each frame which are punched after exposure and processing of the film. The perforations in each frame are located from the normal film perforation and from the edge of the film which is guided during projection. The modification of a standard Bell and Howell perforator for producing this film and a method for checking the accuracy of the finished film are described.
