A virtually transparent magnetic layer is included as an additional layer in a color negative film. Information exchange between various users of the film--such as the camera user, the dealer and photofinisher--is carried via plural longitudinal magnetic tracks on the film, each track being dedicated to the writing and reading of a predetermined set of related parameters. The printing and makeover process of the invention responds to data on the dedicated magnetic tracks on the film to govern the process and uses these tracks as a memory to write and retrieve data governing later steps in the process. The contents of a makeover/reorder instruction track on an initial frame of the film is determined and used, in conjunction with classification and makeover correction data contained in subsequent film tracks, in the printing and makeover process.
