This invention contemplates a prepackaged photographic unit containing a photographic element comprising a transparent polyester film support with improved tongue retrieval performance and acceptable cutting performance in photofinishing equipment.

One-time-use camera containing improved film element

A method and system for photofinishing, includes generating a unique roll ID number for a roll of photographic film to be finished; recording customer order information for the roll of film; associating the customer order information with the unique roll ID number in a central computer facility; marking the roll of film with a machine readable version of the unique roll ID number; and reading the roll ID number on the roll of film, and accessing the customer order information from the central computer facility to control a photo finishing operation, whereby the roll of film can be transported to a photofinishing laboratory without the use of an envelope bearing customer order information.

Photofinishing method and system

A cassette includes a photographic element having a predetermined ISO rating suitable for capturing a plurality of images thereon and identification based on an ISO greater than the predetermined ISO rating. The identification specifically indicates that the photographic element is underexposed and, when developed, is to be processed and printed by a digital print station to correct for the underexposure.
