Abstract: A sheet of x-ray film in a film cassette is identified with patient data by first providing such data to a data carrier, such as an LCD unit, mounted on the cassette and facing away from the cassette. Then the film that is removed from the cassette in a light-tight environment and exposed to the patient data in the data carrier.

Abstract: A camera shutter having a light-responsive circuit that regulates movement of the shutter to effect an exposure of duration related to actual scene brightness, an exposure-limiting device that operates to limit the duration of the exposure to correspond to a predetermined scene brightness, means for selectively disabling the exposure-limiting device, and shutter reset apparatus that, if the exposure-limiting device is disabled during an exposure, reenables the device when the shutter is reset.

Abstract: In a photographic camera of the type having a box-like camera housing and a cover door having a main cover portion which is hinged at one end to the camera housing and a lens support portion on the other end of the main cover portion, a two-part light-tight bellows is provided which couples the cover door with the camera housing in a manner permitting movement of the cover door between a closed position wherein the main cover portion is substantially parallel to one wall of the camera housing and an open position wherein the main cover portion is extended outwardly from the housing at an oblique angle and the lens support portion is substantially parallel to the one wall of the camera housing. When the door is closed, the two-part bellows is collapsed with one part folded flat against the main cover portion of the door and the other part folded flat against the lens support portion of the cover door.
