Description

The invention relates to film photographic techniques, specifically to methods for producing a combined, for example, light-music film by shooting a frame in parts.

The aim of the invention is to simplify the process in obtaining a color image.

The drawing shows a diagram explaining the method.

On screens 1, 2 and 3, separate independent black and white shooting models are continuously reproduced, each of which is shot with a corresponding camera 4.5 and 6 on a black and white negative film, and three independent black and white negatives are obtained; 10, 11, and 12 are positive images on a matrix film, then each matrix is dyed with its corresponding color dye, after which, from the colored matrices 10, 11, and 12, they are sequentially printed on one common transparent film 13 of the Blank-film type. Strongly gidrotipnoy color printing apparatus, and a combined receive frame comprising three colored member 14, 15 and 16.

The shooting models represent on a dark background the bright source objects of the image: in the frame 1 circle; in the frame 2 hexagon, in the frame 3 segment.

After shooting the original objects 1, 2 and 3, three independent black and white negatives 7.8 and 9 are obtained, from which matrices are printed, one of which with the image of the object from the screen of the shooting model 1. is painted yellow (yellow background, transparent circle) , the second with the image of the shooting model

2 paint, for example, in blue color (a blue background, a transparent hexagon), and the third with the image of shooting model

3 color in a transparent color (purple background, prg. Cancer segment). Then, on film with frames 13, after printing the combined matrices 10, 11 and 12, a final combined multicolor image is produced, with a blue circle 14 (purple blue), a red hexagon 15 (yellow + purpl

green) and green segments 16 (yellow + blue). Moreover, frame 13 captures one of the Moments of a color continuously changing in configuration, the direction of motion of the states of the shooting models from which the combined color image was obtained,

It is possible to control the density of the dye on the Matrix both when shooting the original negatives and when printing the matrix itself.

If three matrixes are fabricated with uniform | dye density all over cedar, then a joint print with nmx on a blank film such as Blank-film gives a black color, since in this case the three primary colors are mixed, i.e. successive subtraction from the white color of all existing colors, If on one of the matrices (for example, blue) create a local decrease in the density of the dye in the frame, for example, to zero, then when printing from it on film Blank-film in this place there will be no blue dye. And a red (purple + yellow) enlightenment appears on the former black background of the frame, since in this place the red color is not absorbed by the blue dye

The shape and location of any spot is determined by the image on the black-and-white color-separated negative, from which a matrix is printed, and the density of this image is ultimately determined by the density of the dye at each point of the frame.

When shooting, the exposure is set by the camera's aperture and the degree of illumination of various points on the screen of the shooting model, which is the main method of controlling the density (saturation) of the image color on the final positive film. The color correction is carried out according to the results of visual control of the resulting print on the movie screen at intermediate stages of work. As a result, the final results are obtained in the same way as when the artist works with paints (mixing them overlapping them on canvas), i.e. based on direct artistic experience without digital physical calculations.

Use of montage, double exposure when shooting a film and when printing

matrix and change of negative image to positive allows to obtain the desired extremely complex combinations of variously reduced forms and lines. Additional printing of the image directly from the black-and-white negative to the film. The blank-film allows you to enter free black in the resulting colorful picture.

If you need to get on red

5 background movement of the blue graphic pattern, the graphic pattern form on the oscilloscope screen (Lissajou figure), removed on a black and white film. From this negative, one double and one intermediate black and white positive image are made, a blue matrix is printed from a positive image, a yellow matrix is printed from one negative image, and a purple one from the other.

If you want to get on the background of purple waves the rotation of the blue spiral, in the center of which the black sun pulsates, remove the first black and white negative

5 images of a wavy structure, for example, with the help of light projectors. In the second black and white negative, for example, a rotating spiral is removed from the oscilloscope screen. On the third black-and-white negative, images of a pulsating sun are removed, for example, using light projectors. From this negative print intermediate positive image. 0 Printed matrix from the first film

5 is colored blue, the matrix from the second film is colored purple, the positive image from the third film is yellow. Combined sequential printing gives the desired result.

METHOD FOR PRODUCING A COMBINED IMAGE, which consists in shooting parts of an object, obtaining black and white negatives, and then combining the images of parts of the object in one frame, characterized in that, in order to simplify the method of obtaining a color image, from black and white negatives matrices are made that are dyed with predetermined colors, after which they are combined and printed.
