  • Patent number: 5266994
    Abstract: A method for processing a flexible photosensitive sheet or web material (PSM) including a photographic emulsion on at least one of the flat surfaces thereof and employing a minimum quantity of processing solution including the steps of containing the processing solution in a generally sheet-like geometry, introducing the PSM into the processing solution at a liner face thereof, and substantially immediately upon the entry of the PSM into the processing solution, effecting dispersal of the processing solution onto the emulsion-bearing surface and retaining the solution on such surface for a period of time sufficient to render the surface susceptible to the flow and retention of the processing solution on such surface without external aid. Within the reservoir, the emulsion-bearing surface may be further subjected to one or more further treatments to enhance the development process.

  • Patent number: 5022418
    Abstract: The present invention provides an apparatus and method for processing a sheet material, for e.g. a photosensitive sheet material, with a flowable process substance. The flowable process substance is distributed via a pliable web which has defined on one of its surfaces a plurality of protrusions which define interconnected fluid reservoirs and distribution channels, and which are in surface-to-surface contact with the sheet material over a substantial portion its surface area while the sheet material is transported relative to such web.

  • Patent number: 4977422
    Abstract: The methods and apparatus disclosed herein provide commercially viable means to selectively improve the input and output characteristics of photosensitive materials, especially the output contrast variables. The present invention allows commercially available photosensitive material such as the high contrast Ilford Cibachrome Copy CCO Paper.RTM. to display dramatically improved color balance and contrast range characteristics when making reproductions from slides or prints. Recreational, professional and military photo duplication techniques are greatly improved by the present invention.

  • Patent number: 4970547
    Abstract: A system and method for generating and codifying cropping and enlargement information for a rectangular photograph utilizes at least one transparent overlay and a grid board for underlying the overlay. The overlay includes markings providing a plurality of rectangular windows arranged about a common center and identification indicia for identifying each window and the enlargement multiple necessary to enlarge the window to a predetermined photo size. The grid board has a flat surface bearing a pair of intersecting lines which divide the surface into four quadrants about the center of the board surface, and one quadrant of the board bears a pattern of markings which provides the one quadrant with a two-coordinate grid and indicia for identifying coordinate locations on the grid.
