Description

Method for producing cinematographic scenes. The production photographic scene images with the background recorded separately therefrom is special important for cinematography to create films where the backgrounds moving scenes without the erection of large buildings and without the actors traveling abroad and operators, that is, can be obtained without great expense. One already has for this purpose suggested taking photographs of miniature buildings or of separately copied landscape photographs.

The method according to the invention enables the scene image without Consideration for later copying in of the background and unimpaired to be picked up by a fixed die. Essentially, this is achieved by that the motion picture negative contributes directly to the game scene as a movable cover matrix recording or copying a fixed or moving background negative serves without the need for further copies as intermediate stages, as is the case after a older proposal laid down in the patent literature is necessary.

According to this inventive concept, there are various possible designs of the procedure. For one group, the scene becomes active in front of one black, in the second group in front of an intensely white or luminous (with incident or translucent light) backgrounds, e.g. B. against the sky, taken as a background.

In the first case a negative is created with crystal clear, in the second case with a densely blackened background. In both types of execution, the negative will be expedient to expose from the back and the contrast of scene and background be designed as blatant as possible.

The negative recorded against black with a crystal clear background becomes too translucent in the shadow areas that are still too translucent despite strong exposure are, with a well-covering, easily soluble, z. B. red dye of a brush retouch subject. The dye should be washed out again.

If a negative treated in this way when recording the background serves as a cover template, a developable one becomes on the background negative Exposure or blackening only occur where the cover negative was crystal clear. The background that appears on the second negative is completely worn through the boundaries of the scene image of the cover negative must be determined.

After the development and completion of the expediently somewhat narrower exposure Background negatives are both negatives z. B. by weakening the scene negative brought to the same opacity and as when recording the background with the The sides of the layer are copied together like a single negative by means of projection.

The negative scene shot against a bright background with a blackened background must work with a background negative, which is the one from the scene taken Parts appear heavily blackened. This is because of this achieves that (read scene negative on a normally recorded 1-1 background negative Before developing with the greatest possible light intensity, the parts of the sky just left white, is copied.

In this second method, the contrasts between illuminated scene and bright white backgrounds are not made so blatant can be used as when recording scenes against a black background. To help out here, the background of the production design negative is blackened by the fact that the Negative previously soaked with bichromate was post-exposed for a long time from the celluloid side is until the strong blackening of the scene is completely tanned by the light are. The black background is then still a little (lighter, so that the Tanning does not penetrate completely. The remaining weak, untanned layer is then expediently impregnated with an intense red dye. As in the first embodiment of the method described, a brush retouching can then be done be made. Then suffer negatives again either one after the other or because the play scene requires projected light again, also at the same time (the game scene from the back) can be copied.

The outlines of the scene must at least stand out sharply from the background ; cblift, as in both cases the retouching does not affect the outline allowed.
