Abstract: Photographic images, particularly multicolor images, viewed through a transparent support have an anti-reflection coating on the outer surface of said support. The anti-reflection coating comprises an eighth-wave layer of silica and an eighth-wave layer of a fluorinated polymer. The images may be formed by multicolor diffusion transfer processes using dye developers or other image dye-providing materials. In the preferred embodiments, the photographic image is an integral negative-positive reflection print. Where photoexposure is effected through a transparent support, e.g., the transparent support through which the final image is viewed, provision of an anti-reflection coating and effecting photoexposure therethrough will permit more effective recording of light passing through the camera lens. The transparent support preferably has an index of refraction of at least 1.6.

Abstract: Photographic apparatus, e.g., a camera, for exposing a photosensitive element located in position for exposure within the camera. The camera is provided with temperature responsive structure for preventing the initiation of an exposure cycle when the ambient temperature is outside a predetermined range. In a preferred embodiment, the camera includes a motor connectable to a source of energy, e.g., a battery, for operating various subsystems of the camera, e.g., a shutter, and the aforementioned temperature responsive structure is a bimetallic structure which functions to connect the motor to the source of energy when the ambient temperature is within the predetermined range and to disconnect the motor from the source of energy when the ambient temperature is outside the predetermined range. In an alternative embodiment, the temperature responsive structure takes the form of a resilient bimetallic member which defines one contact of a normally open switch located in an exposure control circuit. During normal operation, the resilient member is manually flexed to close the switch and initiate an exposure cycle. As the ambient temperature changes to a value outside of the predetermined range, the curvature of the bimetallic member increases to a point whereat the member can no longer be manually flexed into a position wherein the switch will be closed.

Abstract: A manually controlled replay system for automatic photographic transparency processing and projection apparatus of the kind adapted to receive cassettes of film each containing a film processor. Such apparatus manipulates the film in the cassette to process it, unless it has already been processed, projects processed film, rewinds the film after projection, and then ejects the cassette. The replay system comprises a manually operable control, effective during the projection of film, to partially or completely rewind the film and reproject selected portions of it.

Abstract: Projector apparatus employing a cassette-latching shaft member which automatically locates and locks a photographic cassette in an operative location responsive to insertion of the cassette in a cassette-receiving element of the apparatus. Displacement of the shaft member to its cassette-locking position allows engagement of other cooperating elements of the apparatus with the cassette and initiates operation of the latter through a preprogrammed sequence for projection including transport of the film in a forward and rewind direction. Following completion of the film rewind, the cooperating elements and the shaft member are automatically disengaged from the cassette, the latter is partially ejected and the apparatus turned off. The apparatus is also configured for operation of a multipurpose cassette which includes a processor station adapted to apply processing fluid to the film strip during its first rewind following exposure, and when the cassette is unprocessed, the apparatus automatically processes the cassette during the first film transport cycle and repeats the cycle prior to cassette ejection so as to program the latter through both a process and projection mode.

Abstract: A photographic system, comprising a film cassette containing a strip of film, a supply of processing composition, and a processor programmed to apply the processing composition to the film upon manipulation of the film in the cassette; and a film drive and projection system adapted to receive the cassette, and containing cyclic drive means responsive to the insertion of a cassette and to a signal produced by the cassette indicating whether or not the film has been processed for manipulating the film, to cause processing if the film has not been processed, and then to project it; or simply to project the film, if it has been processed. To process the film it is rewound a distance sufficient to release the processing fluid. The film is then stopped for an interval sufficient to allow the processing fluid to reach the film before rewinding is continued.
