Abstract

FIELD: cine-phototechnology. SUBSTANCE: process of manufacture of cine-photomaterials includes application of two light-sensitive layers on backing sensitive to radiation of different parts of spectrum. One layer contains color-forming dye which color adds to color of enhanced part in positive image. The other light-sensitive layer carries mixture of light blue, purple and yellow color-forming components. Due to insertion into manufacturing process of film of new operations capability to form black-and-white image of multicolored object with enhanced color part of object during one exposure is obtained. This contributes considerably to creative possibilities of makers of movies and artistic photographs. EFFECT: expanded creative capabilities of makers of movies and of artistic photographs.

Description

 The invention relates to methods for producing multilayer film materials that can be used to obtain color and black and white images in films and photographs.

 Known methods for the manufacture of color film photographs, allowing to obtain color images (ed. St. USSR N 165971, CL G 03 C 7/20, 1961; ed. St. USSR N 193923, CL G 03 C 7/26, 1966; ed St. USSR N 901988, class G 03 C 7/22, 1977).

 The known methods are based on layer-by-layer deposition on a substrate of three photosensitive layers with different color components (cyan, magenta, and yellow). The use of such films in cinematography provides images with the transfer of colors close to natural.

 Closest to the proposed invention is a method of manufacturing a spectrozonal film SN-6 (TU-6-17-688-70) produced by the Svema postal plant of the Shostkinsky Chemical Plant (Butovsky YL Non-typical films and processes in artistic cinematography. Film technology and Television, 1979, N 2, p. 24, 25).

 The CH-6 film is based on the sequential deposition of two photosensitive layers: the lower sensitized (sensitive) to invisible infrared radiation and containing one color-forming component and the upper sensitive to the visible part of the spectrum and containing one color-forming component, different from the lower layer component.

 Using a film made in this way allows you to get a color image of a multicolor object in arbitrary colors. For example, such a film is used for aerial photographs, in particular, for decoding the water and plant surfaces. Sometimes the effect created by such a film is used in artistic cinematography, for example, when shooting the movie "The Scarlet Flower".

 However, the well-known two-layer film does not allow one exposure to a black and white image of a multicolor object with a color image of an individual part of the object, which can be dictated by the creative tasks of the authors of the film.

 Currently, frames that include both black and white and color images are obtained using complex technological processes of shooting and expensive complex television and photo equipment, for example, the widely known method of shooting a wandering mask.

 The purpose of the invention is the creation of a film with new properties other than known, a change in the production parameters of the film due to the introduction of changes in the technological process of its manufacture.

 The use of a film made by the proposed method will make it possible to obtain in one exposure a positive black-and-white (monochrome) image of a multicolor object and a color image of the selected part (detail) of the object directly in contact with it.

 The second photosensitive layer is created by three components used in conventional color films (yellow, magenta and cyan), but in known methods, these components are applied to the substrate separately in three layers, each component in the corresponding layer.

 In contrast to the known methods for the manufacture of film and photo materials in the proposed method, a mixture of all three components is applied in a single layer. With the color manifestation of such a film in the specified layer, a neutral (monochrome) image is formed.

 The first (lower) layer used in the proposed method should contain any color-forming component that forms, when developing, a dye of an additional color to the color of the highlighted part of the object or to the color in which this part should be painted in a positive image according to the artist’s creative plan. This first layer should have a spectral sensitivity not covered by the sensitization zone of the second layer, but to which the color of the highlighted object detail is active. This method can be used with film and other carriers of silver halide photosensitive layers in both negative-positive and reversible processes.

 The purpose of the invention is achieved in that in a method for producing a photographic material comprising applying two photosensitive layers sensitive to radiation of different parts of the spectrum onto a substrate, a photosensitive layer is applied to the substrate containing a colored color-forming component, the color of which is complementary to the color of the highlighted part in a positive image, and a photosensitive layer containing a mixture of cyan, magenta and yellow color-forming components.

 PRI me R. According to the creative task of the authors of the film, it is necessary to depict the urban winter landscape in a graphic manner with a working red traffic light. In this case, one should choose a photosensitive material with three color components of a conventional color negative film in a “black and white” layer with a blue-green spectral sensitivity and a color red-sensitive layer with a blue component.

 It is possible to achieve the correct light organization of the object being shot onto the film of multi-shading of the highlighted colored parts thereof.

 Thus, the proposed method for the manufacture of film material allows you to get a film with new properties. Using such a film, it is possible to form frames in one exposure, including black-and-white and color images of a multicolor object, without using complex equipment and complicated technology for forming combined frames, only by changing the technology for forming combined frames.

 The choice of sensitization of layers and color components, as well as the organization of illumination of an object in each individual case, is dictated by the creative tasks of artists and the requirements for image quality.
