Abstract
A single use camera is preloaded with a roll of magnetically coated film with defined image frames. The camera has an exposure system for selectively exposing an image frame of the film in one of a plurality of image formats. The camera also includes a manually actuated mechanism coupled to a mounted permanent magnet. The magnet is movable to record a magnetic mark on the magnetically coated film at a predetermined location relative to an exposed image frame. The location of the mark is indicative of the image format of the exposed image frame.
