  • Patent number: 6503670
    Abstract: A process for restoring the color of faded color negative film, particular for faded color motion pictures. The original faded negative film is used to produce a green enhancement mask and a blue enhancement mask (or a combination green/blue enhancement mask). Standard red, green, and blue separations are also made from the original faded negative. By combining the green and blue enhancement masks with the standard green and blue separations, respectively, (or the combination green/blue enhancement mask with the green separations and blue separations), enhanced green and blue separations are created. The enhanced green separation, the enhanced blue separation, and the red separation are recombined to form the restored color negative or interpositive. Alternately, from the original negative, an enhanced blue mask can be created, and intermediate film stock printed with yellow light passed through the original negative to produce unprocessed intermediate stock can be created.

A photographic system is also described that produces a photograph with a 3-dimensional image from 2-dimensional cross sections of a subject; the system is useful in medical imaging. During exposure, motion of more than one wavelength of light is permissible between the subject and lens or the lens and the photo-sensitive element.These improvements result from the use of a particular type of angular reflector which is a retro-reflecting sheet.

  • Patent number: 4980262
    Abstract: A photographic contact printing process is disclosed having application in the mass production of replicate video discs from a master disc, and other applications wherein it is desired to replicate micro-detail over a relatively large area. A problem with conventional contact printing from a mask to a photographic medium is one of maintaining intimate contact over a relatively large area since dust, dirt, etc., are almost impossible to completely eliminate in any practical manner. In accordance with the present invention, a contact printing process is provided wherein intimate contact is not necessary for making high quality contact prints. The present invention recognizes that in contact printing information from a master disc to a replicate disc, the contact printing process is significantly less sensitive to imperfect contact between the master disc and the replicate disc if one employs a replicate disc comprising a photosensitive material having a certain optical properties.

    Abstract: Disclosed is a method of preparing and printing custom artwork such as, for example, photo greeting cards, allowing the creation of calendars, business cards, and the like using a plurality of colors. In the method, after all of the preparatory typesetting and artwork has been completed, special color filters are adhered to the base side of the high contrast film negative which is created from the pasted-up type and artwork. These filters are chosen based upon the desired finished product colors. The final color created is the photographic complement of the filter(s) used.

  • Patent number: 4888266
    Abstract: The invention relates to a process for producing supports intended for the optical recording and reading of information. A layer containing a diazo compound is deposited onto a metallized substrate. Recording is obtained by exposing the support to light through a mask, the exposed zones of the layer of diazo compound being decomposed. Dry development in ammonia vapors shows up transparent zones and opaque zones corresponding to the information.

  • Patent number: 4835090
    Abstract: The invention discloses that a photograph with a 3-dimensional image results when the non-angular reflector (of mercury) used in the Lippmann process of color photography is replaced by an angular reflector; the preferred form of the angular reflector is a retro-reflector.A photographic system is described which produces photographs with 3-dimensional images. The photo-sensitive element records the interference patterns of light waves, and the system is an improvement over the Lippmann process of color photography which produces photographs with 2-dimensional images. A photographic system is also described that produces a photograph with a 3-dimensional image from 2-dimensional cross sections of a subject; the system is useful in medical imaging. During exposure, motion of more than one wavelength of light is permissible between the subject and lens or the lens and the photo-sensitive element.These improvements result from the use of a particular type of angular reflector which is a retro-reflecting sheet.

  • Patent number: 4777102
    Abstract: A method for electronic "dry" development of latent images in conventional types of color photographic films comprising interrogating the film with a series of different color light beams, each corresponding in color frequency with a different color sensitivety of the film and each having a time-amplitude energy content that is sufficient to drive that latent color image in the film into a condition of saturation. Deriving from each of said different color interrogations an electrical signal, corresponding to the latent image in that color, and recording said electrical signals. An apparatus for performing said method comprises a portable, light tight enclosure, containing a series of different color interrogating light beam generating mechanism, light energy detectors, and electrical recorders.

  • Patent number: 4764454
    Abstract: A novel silver halide color photographic material is provided comprising a compound of the general formula (I):LIG-A-LVG (I)wherein A represents a group which reacts with an oxidation product of a developing agent to cleave the bond to LVG; LVG represents a coupling-off group; and LIG represents a group which reacts with metal ions to form a complex compound.A novel method of processing the instant silver halide color photographic material is provided including a processing step using a processing solution of an iron (II) ion concentration of 1.times.10.sup.-6 to 1 mol/l. In the processing step, the potential of a bath having a bleaching capacity containing an aminopolycarboxylic acid-iron (III) complex salt is 150 mV or less.

  • Patent number: 4737448
    Abstract: Method and apparatus for full-color reproduction of a continuous tone color picture or scene using multiple diffraction gratings. The reproduction consists of a plurality of small diffraction gratings (70). A plurality of color separation masks (60) are created for each unique scene. Those picture elements in the original scene containing a given primary color are captured in these transmission-type masks. In certain zones dictated by the separation masks, a plurality of interference patterns are recorded in the properly photosensitized media (70). The spatial freqency of said interference patterns correlates to the primary color to be reproduced. These interference patterns become multiple diffraction gratings when properly developed. The properly photosensitized media may be used as a master for replication purposes. When either master or replica (78) are properly illuminated in white light (76) and properly viewed, the multiple diffraction gratings act to reproduce the colors in the original scene.

  • Patent number: 4609613
    Abstract: Permanent gray-scale reproductions including half-tone images. A refractory background region bears refractory thin-film dichroic filter means patterned to conform to the reproduced half-tone image. Preferred background region materials include metals, semiconductors, and ceramics; the thin-film materials are preferably oxides or nitrides of metals and semiconductors. If the refractory materials are appropriately selected, the reproductions are highly resistant to chemical and thermal deterioration and should have useful lives in the hundreds of thousands of years.
