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.
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 ...
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 ...
Introduced around 1940, in sheets rated at ASA daylight 200 and tungsten 160, it was one of Kodak's first high-speed (for the time) black and white films. Tri-X was released in 35 mm and 120 formats in 1954. Currently it is available in two speeds, ISO 320/26° (320TXP) and 400/27° (400TX).
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'.
The effective speed of a digital camera can be adjusted at any time, while the film must be changed in a film camera to change the speed. [citation needed] However, film is available in much lower film speeds than digital which rarely drop below ISO's of 100 or 400, a number of both colour and black & white films are sold with ISO of 50, this ...
The 100 and 400 speeds are given as ISO numbers, but the 3200 is sold as a multi-speed film. [2] T-MAX 100, due to its very high resolution of 200 lines/mm, is often used when testing the sharpness of lenses. In early 2002, Kodak replaced its similarly titled Kodak T-MAX Professional Film with Kodak Professional T-MAX Film. [3]
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.
