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 ...

In the traditional photochemical post-production workflow, release prints are usually copies, made using a high-speed continuous contact optical printer, [5] of an internegative (sometimes referred to as a 'dupe negative'), which in turn is a copy of an interpositive (these were sometimes referred to as 'lavender prints' in the past, due to the slightly colored base of the otherwise black-and ...
