A Techniscope camera film frame. Techniscope or 2-perf is a 35 mm motion picture camera film format introduced by Technicolor Italia in 1960.

Aaton Penelope is a 35mm motion picture camera introduced by Aaton in October 2008. It is the first camera in the world designed as a switchable Techniscope or 3-perf shooting solution (2 perf-native and 3 perf user-switchable), and it is also the first 35mm camera to offer a progressive scan video-tap.

The majority of 35 mm film systems, cameras, telecine equipment, optical printers, or projectors, are configured to accommodate the 4-perf system; each frame of 35 mm is 4 perforations long. 4-perf was (and remains) the traditional system, and the majority of projectors are based on 4-perf, because 4 perforations is the amount needed per frame vertically in order to have enough negative space ...

Although a very early pioneer in trichromatic color film (as early as 1908), invented by German chemists Rudolf Fischer and Benno Homolka [], Agfa film was first made commercially available in 1936 (16 mm reversal and 35 mm), [2] Agfa-Gevaert has discontinued their line of motion picture camera films.
The projection aperture height was also reduced by 0.01 inches (0.25 mm) to give an aperture size of 0.825 × 0.690 inches (20.96 × 17.53 mm), and an aspect ratio of 1.1956…∶1, and thus retaining the un-squeezed ratio of about 2.39∶1. [13] The camera's aperture remained the same (2.35∶1 or 2.55∶1 if before 1958), only the height of ...
