30 giug 1926 anni - 1926 - Rear Projection

Descrizione:

The film "Metropolis" was the first to use of rear projection with a moving background image. This method combined live-action foregrounds with pre-filmed background scenery. Actors perform in front of a translucent screen which has still or moving images projected on to it from behind and another camera films the composite image. These are then put together to create the completed image.
