ABSTRACT:
In accordance with the present invention, a method for advancing photographic film is provided for use by a photographic system which uses film cartridges, such as cameras, film development equipment or equipment which provides for the viewing and/or printing of processed film contained within a film cartridge. The method can be used by a dual lens camera to intersperse on photographic film mono and dual exposures and thereby minimize the possibility of double exposures and/or film waste. The method according to the present invention is for use by the camera to advance the film after each exposure action to align unexposed frames of film with each lens. In accordance with one embodiment of the present invention, the dual lens camera is capable of tracking whether the next frame has been exposed and the frame following the next frame has been exposed and advancing the film one frame if the next frame is unexposed; two frames if next frame is exposed and the frame following the next frame is unexposed; and three frames if the next frame is exposed and the frame following the next frame is exposed. The method of the present invention can also be used by a hand-held viewer capable of displaying images on processed film containing interspersed mono and dual images to advance the processed film to minimize the possibility of the viewer displaying such images in duplicity.
