Zusammenfassung: | A method for monitoring the amount of unexposed photographic film remaining in a motion camera film magazine that includes the steps of: providing an unexposed motion picture film containing a support having at least one light sensitive image recording layer and a transparent magnetic recording layer; recording film length data on the transparent magnetic recording layer of the unexposed motion picture film; loading the unexposed motion picture film in a motion picture film magazine; and reading the film length data from the transparent magnetic recording layer as it is removed from the film supply magazine to provide an indication of the amount of unexposed film remaining in the motion picture film magazine. The amount of unexposed film remaining may be displayed in a read-out device associated with the film magazine or camera. |
