Zoptic
The Zoptic mechanism is a form of front projection . It was invented by animation specialist Zoran Perisic and first used in the films Superman with Christopher Reeve and Oz - Eine fantastische Welt . In the projector and the film camera are during the filming variable focal lengths with synchronized zoom and automatic iris for individual adjustment of each used light intensity attached. It is thus possible, by changing the zoom setting on the projector, to obtain a different projection image with the foreground remaining the same in the specified image section and to vary it again and again. This makes it possible to statically place objects or people in front of the front panel and create the illusion of a flight / driving effect around them. If the Zoptic device is moved laterally, it gives the impression that z. B. a UFO on the way or can disappear.
