Abstract

255,061. Akt.- Ges. f³r Spiegeltechnik, (Assignees of Kohler, W.). July 10, 1925, [Convention date]. Kinematograph picture films; composite photographs.-In apparatus for taking photographs or films in which part of the scene is produced by reflection, the mirror 6, Fig. 1, is placed so near the camera 2 that the outline between the transparent part 8 and the reflecting part 7 of the mirror is reproduced as an indistinct image or band which partially obliterates the transition zone between the part scenes 3, 5, which are arranged to overlap. This outline may only approximately follow the division. line 4. Fig. 2, within the transition zones. The mirror is adjustably mounted according to the lens used and the dispositions and areas of the part scenes. To ensure the sudden disappearance of an actor at the edge of the scene 3, a shield or mask 12 is used and so placed as to be sharply focused in the camera outside the transition zone between the scenes. The part scenes ca.n be taken simultaneously or independently. and when the part scenes are constructed on different scales, enlarging or reducing lenses or mirrors 13, Fig. 5, may be used between the mirror and the part scene, the edges 14 of such lenses being covered either by the mirror coating or by a non-actinic mask.
