ABSTRACT:
A process for recording camera and exposure information on photographic film, reading the information during photofinishing and re-recording the information magnetically on the film. According to one feature, disclosed with a single use camera, the process includes the ordered steps of recording camera capabilities on the film and then loading the film into a camera having those capabilities. The process further includes the steps of exposing the film in the camera to a scene, processing the film to develop and print the scene using the recorded camera information and re-recording the information magnetically on the film. According to another feature of the invention, disclosed with multiple use cameras, the camera optically records exposure information on the film. The photofinishing operation then reads the optically recorded information, uses the information and magnetically re-records the information on the film.
