Correcting By Color Image Produced By Oxidizing Bath Treatment Patents (Class 430/361)
  • Patent number: 6969581
    Abstract: A method and apparatus for restoring to chemical stability motion picture film having an acetate base which is suffering, or which may begin to suffer, from the deterioration generally referred to as “vinegar syndrome.” The method allows films to be treated and stabilized without applying a liquid to their surfaces and without immersing them in any liquid. Instead, vapors emitted from a specially prepared, heated chemical solution permeate the film base and begin chemical reactions which ultimately restore the film. The process can be used on film that has begun to deteriorate, or it can be used, as a preventative measure, on apparently healthy film.

  • Publication number: 20040126716
    Abstract: Rapid development of silver bromoiodide color negative photographic films and formation of high quality negative images suitable for scanning to produce display images of excellent quality is made possible by a novel developer solution composition and method of development. The solution is characterized by containing, in addition to the color developer compound and conventional photographic developer solution components, a water soluble pyrrolidone polymer, a high concentration of sulfite ion and a low concentration, or the absence of, bromide ion. In the novel method the developer composition contacts the exposed film at elevated temperature, e.g., 40 to 66° C., for a short development time, e.g., 20 to 90 seconds. The developed image has image quality suitable for scanning and digital manipulation to produce a digital record for forming a color display image of high quality.

  • Patent number: 6537737
    Abstract: A method and apparatus for restoring and enhancing both color and black and white motion picture films. In accordance with the method of the invention, vapors emitted from a heated chemical solution, but is not, at any time, immersed into the chemical solution. The identical process is used in enhancing both color and black and white films. Enhancement of black and white films in accordance with one form of the invention includes an expansion of the contract range of the film, turning murky grays into deep blacks, bringing out textures in set and costume design, and revealing artistic lighting effects that were either muted or lost. Optical soundtracks on black and white films are also improved by the method of the invention.

  • Patent number: 4678740
    Abstract: A photographic matte for use in traveling matte photography is formed by recording a separation of a first screen-color separation of an image on a first film layer and recording a separation of a different second color on a second layer. Preferably, the second color is complementary to the screen color. One layer is developed to form a positive image and the other to form a negative image, these images reinforcing each other. One image is formed by black dye, using a coupler and a color developer and the other is formed by a black dye destruct technique in which the developed portion of the silver halide emulsion is removed. According to another aspect of the invention, a matte of increased density can be formed without commensurate image growth by combining a black dye image with a silver image.
