Multiplane Camera

A motion-picture camera rig that holds several layers of artwork at different distances from the lens and moves them independently, so the further layers shift more slowly than the near ones, producing an illusion of depth and parallax in traditional animation. William Garity's advanced version for Walt Disney Studios, completed in early 1937, was tested in the Silly Symphony The Old Mill before its full use in Snow White and the Seven Dwarfs, though Lotte Reiniger had already used a multi-layer glass setup in 1926 and Ub Iwerks built his own rig in 1933.
