The ASA scale is a linear scale, that is, a film denoted as having a film speed of 200 ASA is twice as fast as a film with 100 ASA. The ASA standard underwent a major revision in 1960 with ASA PH2.5-1960, when the method to determine film speed was refined and previously applied safety factors against under-exposure were abandoned, effectively ...
The amount of silver in the film stock was reduced. [6] [7] Tri-X also exists as a reversal film for the 16 mm and Super-8 cine film formats. The speed for tungsten lighting (3200 K) is ISO 160 and for daylight ISO 200 when processed as reversal. It can also be processed as a negative at a small loss of speed while the grain will be slightly ...
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.
The first DX encoded film to be released was the color print film Kodacolor VR 1000 in March 1983. The first point-and-shoot cameras to use DX encoding to automatically set film speed were released in 1984, including the Pentax Super Sport 35 / PC 35AF-M [ 5 ] and Minolta AF-E / Freedom II. [ 6 ]
135 film. The film is 35 mm (1.4 in) wide. Each image is 24×36 mm in the most common "small film" format (sometimes called "double-frame" for its relationship to the "single-frame" 35 mm movie format or full frame after the introduction of 135 sized digital sensors; confusingly, "full frame" was also used to describe the full gate of the movie format half the size).
(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.
One foot of standard 35mm film contains 16 frames, and a standard recording speed is 24 frames per second, or 1.5 feet per second; a 90-minute feature film shot in this way on conventional film stock is therefore equivalent to more than a mile and a half of footage.

A cartridge of Kodak 35 mm (135) film for cameras. A film format is a technical definition of a set of standard characteristics regarding image capture on photographic film for still images or film stock for filmmaking. It can also apply to projected film, either slides or movies. The primary characteristic of a film format is its size and shape.
