<p>Apparatus in a simple low cost camera for encoding the existence of pseudo format image exposures on film having a magnetic layer (26) thereon with prerecorded data in one or more parallel tracks (40, 42, 44) on the film. A user operable means on the camera establishes the existence of a pseudo tele or pseudo pan image frame and actuates one or more permanent magnets into contact with one or more prerecorded data tracks on the magnetic recording layer to cause selective erasure of track segments on the film associated with the pseudo format film image frame as the film is advanced to the next frame position. The absence of data in the track segments provides an indication on the film of a desired pseudo format which can be detected by the printer during the photofinishing process to reproduce the appropriate pseudo format print.</p> |
