摘要:
A photographic material processing apparatus and method provides for a homogeneous application of processing solution which leads to homogeneous development. The apparatus utilizes a spreader member in the form of, for example, a spreader bar that applies a limited quantity of developer solution to photographic material such as imagewise exposed film. A pressure member in the form of, for example, a weighted roller or spring-loaded roller acts a squeegee roller and improves contact of the film with a support and/or a heating source. A roller arrangement which includes at least the spreader member and pressure member is configured to enable multiple contacts of the spreader member and pressure member with the photographic material to aid in the agitation of the applied developer solution. In a further embodiment, an additional member in the form of, for example, a mixer member can be utilized to further agitate the applied solution.

This invention relates to packaged photographic film that is capable of being alternately processed, according to individual consumer choice, by either (1) a traditional wet-chemistry process with a phenylenediamine-containing developer solution followed by desilvering in one or more subsequent solutions to obtain a color negative film, or (2) a thermal process involving the use of a relatively minor amount of an aqueous solution containing a liberating agent such as alkaline base to activate (unblock) a blocked phenylenediamine developing agent located within the photographic element, followed by electronic scanning of the developed film without desilvering. This invention enables a single film stock to be developed in both a conventional deep tank process and in an apparently dry process.
摘要:
Image formation in photosensitive materials can be simplified by photoprocessing the imagewise exposed materials using photochemical delivery articles that consist essential of nonporous substrate and a hydrogel that contains the one or more photochemicals needed for image formation. The delivery articles can be laminated or other wise contacted with the imaged photographic materials on the silver halide emulsion side allowing photochemicals to diffuse into and out of the materials for the desired chemical reactions. Multiple delivery articles can be used in sequence to provide the desired sequence of photochemical reactions.
摘要:
A method of creating image-bearing electronic signals from an imagewise exposed and processed color negative photographic element is disclosed. The color element is especially suited for preloading in a one-time-use camera and is capable of producing images that, when scanned, converted to electronic form and then converted to a viewable form, exhibit excellent color, reduced granularity and improved sharpness. The photographic elements contain blue, green and red recording layer units capable of forming spectrally differentiated dye images. The layer units are substantially free of colored masking coupler, and each exhibit a dye image gamma of less than 1.5. The element exhibits an exposure latitude of at least 2.7 log E. The gamma ratios of the blue, green and red recording layer units are between 0.80 and 1.2.

A color negative silver halide photographic element is disclosed that is capable of producing images that, when converted to electronic form and then converted to a viewable form, exhibit reduced granularity. The photographic elements contain blue, green and red recording layer units capable of forming spectrally differentiated dye images. The layer units are substantially free of masking coupler, each exhibit a dye image gamma of less than 1.5 and an exposure latitude of at least 2.7 log E. Greater than 50 mole percent of development inhibitor compound in at least one of the layer units exhibits a diffusion factor of less than 0.4.
摘要:
Silver chloride color negative films can be rapidly processed using shortened color development times and specific amounts of color developing agent and bromide ion. After development, and optionally desilvering or fixing, the developed film is scanned to form density representative digital signals for the color records. These signals are then digitally manipulated to correct both interimage interactions and gamma mismatches around the color records to produce a digital record that is capable of providing a display image having desired aim color and tone scale reproduction. That digital record can then be stored or used to provide corrected display images, such as color prints, using output display devices.

This invention provides an accelerator for peracid bleaches used for bleaching silver halide photographic elements. The accelerator is a complex of ferric (Fe III) ion and a 2-pyridinecarboxylic acid or a 2,6-pyridinecarboxylic acid. The accelerator may be contained in the bleaching solution, a solution preceding the bleaching solution or in the photographic elements themselves.

This invention relates to cameras designed for single or limited use. It more particularly relates to cameras that are intended for one use, after which they are recycled, subsequent to removal of the film for development and printing or scanning. The camera and film combinations provide exceptionally sharp images.
