35 mm film is a film gauge used in filmmaking, and the film standard. [1] In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips 1.377 ± 0.001 inches (34.976 ± 0.025 mm) wide.
Taken and copyrighted by W. K. L. Dickson for Thomas A. Edison. Although this composite photograph is the oldest paper print of a motion picture known to survive, the vast majority of works in the Library of Congress Paper Print Film Collection are rolls of paper strips 35 mm wide.
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 ...
(A) Human-readable Keykode number (the number to the far right advances by one for each 16 frames of 35 mm film or 20 frames of 16 mm film). Next to that is the same information in USS-128 Barcode machine-readable language. (B) Further down the film (within the 16 frames) is the film identifier information and date symbol (C) Other-use symbols.
The scanned footage is edited and composited on work stations then mastered back on film, see film-out and digital intermediate. Scanned film frames may also be used in digital film restoration. The film may also be projected directly on a digital projector in the theater. The data film files may be converted to SDTV (NTSC or PAL) video TV systems.
Some software used to process images scanned by film scanners allows for automatic color correction based on the film manufacturer and type. In many cases the source film may not be marked with this information in human-readable form, but might be marked at the bottom edge with a DX film edge barcode following a standard maintained by ANSI and I3A.
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 ...
Phototypesetting machines project characters onto film for offset printing. Prior to the advent of phototypesetting, mass-market typesetting typically employed hot metal typesetting – an improvement introduced in the late 19th century to the letterpress printing technique that offered greatly improved typesetting speed and efficiency compared to manual typesetting (where every sort had to be ...
