    Abstract: ING THE PH OF THE PROCESSING COMPOSITION TO A SECOND PH AT WHICH THE DYE IMAGE-FORMING MATERIAL IS SUBSTANTIALLY NONDIFFUSIBLE SUBSEQUENT TO SUBSTANTIAL DYE TRANSFER IMAGE FORMATION IN THE RECEPTION LAYER.

    THE FILM UNITS ADDITIONALLY INCLUDE, IN COMBINATION, MEANS FOR INTERPOSING, SUBSEQUENT TO PHOTOEXPOSURE OF THE SILVER HALIDE LAYER, INTERMEDIATE THE SILVER HALIDE LAYER AND THE RECEPTION LAYER, AN OPACIFYING AGENT IN A CONCENTRATION EFFECTIVE TO MASK DYE IMAGE-PROVIDING MATERIAL ASSOCIATED WITH THE PHOTOSENSITIVE LAYER OF PREFERABLY COMPRISING AN INORGANIC REFLECTING PIGMENT DISPERSION CONTAINING AT LEAST ONE OPTICAL FILTER AGENT IN A CONCENTRATION EFFECTIVE TO PROVIDE A LAYER EXHIBITING OPTICAL TRANSMISSION DENSITY >$6.0 DENSITY UNITS WITH RESPECT TO INCIDENT RADIATION ACTINIC TO THE PHOTOSENSITIVE SILVER HALIDE LAYER AND OPTICAL REFLECTION DENSITY
    THE PRESENT INVENTION RELATES TO PHOTOGRAPHY AND, MORE PARTICULARLY, TO REFLECTION TYPE DIFFUSION TRANSFER PROCESS PHOTOGRAPHIC FILM UNITS WHICH COMPRISE A COMPOSITE PHOTOSENSITIVE ELEMENT ADAPTED TO PROVIDE, BY DIFFUSIN TRANSFER PHOTOGRAPHIC PROCESSING, SELECTIVE INTEGRAL NEGATIVE AND POSITIVE IMAGE RECORDATION OF INCIDENT ACTINIC RADIATION AS A FUNCTION OF THE POINT-TO-POINT DEGREE OF PHOTOSENSITIVE ELEMENT EXPOSURE, WHICH ELEMENT INCLUDES A PLURALITY OF SEQUENTIAL LAYERS INCLUDING A DIMENSIONALLY STABLE LAYER PREFERABLY OPAQUE TO INCIDENT ACTINIC RADIATION; A PHOTOSENSITIVE SILVER HALIDE LAYER HAVING ASSOCIATED THEREWITH DYE IMAGE-FORMING MATERIAL WHICH IS DIFFUSIBLE DURING PROCESSING AS A FUNCTION OF THE POINT-TO-POINT DEGREE OF SILVER HALIDE LAYER EXPOSURE TO INCIDENT ACTINIC RADIATION; A LAYER ADAPTED TO RECEIVE IMAGE-FORMING MATERIAL DIFFUSING THERETO; AND A DIMENSIONALLY STABLE LAYER TRANSPARENT TO INCIDENT RADIATION.

    Abstract: An interface between a film container and a reflecting member mounted within a camera of the single-lens reflex type for defining a lighttight seal substantially at or closely adjacent to the exposure plane of the camera. The camera includes a chamber for receiving a film container, a reflecting member mounted for movement between a first position in which it is located substantially parallel with and closely adjacent to the camera''s exposure plane containing a photosensitive element and in which it cooperates with the film container to form a lighttight seal about the photosensitive element and a second position in which it directs an image toward the photosensitive element located in position for exposure within the film container. The lighttight seal allows access to the interior of the camera to be made without prematurely exposing one of the photosensitive elements.

    Abstract: PHOTOGRAPHIC APPARATUS FOR PROCESSING AND EXHIBITING COMPOSITE, EXPOSED PHOTOSENSITIVE ELEMENT TO PRODUCE A MOTION PICTURE SEQUENCE IN FULL COLOR. THE AUPARATUS INCLUDES A LIGHT SOURCE AND A SUBSTRACTIVE COLOR FILTER SCREEN FOR EXPOSING THE PHOTOSENSITIVE ELEMENT TO FOG PORTIONS THEREOF; LIQUID CONTAINERS AND A FILM DRIVE SYSTEM FOR TREATING THE EXPOSED AND FOGGED PHOTOSENSITIVE ELEMENT WITH A LIQUID REAGENT TO FORM VISIBLE REVERSAL IMAGES THEREIN EACH REPRESENTING A PRIMARY COLOR COMPLEMENTARY TO ONE OF THE SUBSTRACTIVE COLORS; AND AN OPTICALS SYSTEM FOR TRANSMITTING LIGHT FROM THE SOURCE THROUGH THE PROCEED PHOTOSENSITIVE ELEMENT TO PROJECT THE IMAGES ONTO A SCREEN. EACH OF THE VISIBLE REVERSAL IMAGES IS EXHIBITED IN LIGHT OF THE PRIMARY COLOR REPRESENTED THEREBY BY A FILTER IN THE PROJECTOR OR BY UTILIZING A PROJECTION SCREEN WITH COLORED LINES AND REGISTERING THE PROJECTED IMAGES IWTH THE APPROPRIATE LINES. A SYSTEM INCLUDING PHOTOELECTRIC SENSORS ON THE SCREEN AND SERVOS IN THE PROJECTOR ASSURES PROPER REGISTRATION.
