Techniscope or 2-Perf is a 35mm motion picture camera film format introduced by Technicolor Italia in 1963. The Techniscope format uses a two film-perforation negative pulldown per frame, instead of the standard four-perforation frame usually exposed in 35mm film photography. Techniscope's 2.33:1 aspect ratio is easily cropped to the 2.39:1 widescreen ratio, because it uses half the amount of 35mm film stock and standard spherical lenses. Thus, Techniscope release prints are made by anamorphosizing and enlarging each frame by a factor of two.
