The film speed dial of the Canon A-1 (1978) supported a speed range from 6 to 12800 ASA (but already called ISO film speeds in the manual). [55] On this camera exposure compensation and extreme film speeds were mutually exclusive.
High-speed film cameras can film up to a quarter of a million fps by running the film over a rotating prism or mirror instead of using a shutter, thus reducing the need for stopping and starting the film behind a shutter which would tear the film stock at such speeds. Using this technique one second of action can be stretched to more than ten ...

Slow speed panchromatic film with high contrast. The edge markings show an ORWO DP31 duplicating positive film. [157] [158] Germany: 135 Lomography: Babylon Kino: 2020-P: 13: B&W: Print: Slow speed panchromatic film with soft contrast, sharp detail, low grain and subtle gradient transitions based on a 'German cinema film'.
Using ISO convention film with an ASA speed of 400 would be labeled 400/27°. [29] A fourth naming standard is GOST, developed by the Russian standards authority. See the film speed article for a table of conversions between ASA, DIN, and GOST film speeds. Common film speeds include ISO 25, 50, 64, 100, 160, 200, 400, 800 and 1600.
Muybridge's photographic sequence of a race horse galloping, first published in 1878. High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive ...
The film speed codes are in binary order if the first three bits (S1, S2, S3) are considered to identify a trio of film speeds and the last two bits (S4 and S5) are considered an adjustment of +0, + 1 ⁄ 3, or + 2 ⁄ 3 stops within that trio. For example, ISO speed 25/15° is encoded as 00010, while 32/16° is 00001 and 40/17° is 00011.
Silent film has no standard speed; many amateur formats have several common speeds, but no standard. Negative lenses indicates whether spherical (normal) or anamorphic lenses are used on the original camera negative, and if anamorphic lenses, what anamorphic power is used. Projection gauge is the film gauge (width) used for the release print.
