ISO: A system for quantifying the sensitivity ("speed") of a photographic emulsion, or a solid-state digital-camera's image sensor, to visible light. Normally followed by a numerical value, e.g.: ISO 100 or ISO 64/19°. Developed from the ASA and the DIN systems by the International Organization for Standardization. [4] JPEG
It has developed various standards, which have been published by ITU-T and/or ISO/IEC. The standards developed by the JPEG (and former JBIG) sub-groups are referred to as a joint development of ISO/IEC JTC 1/SC 29/WG 1 and ITU-T SG16. The JPEG standards typically consist of different Parts in ISO/IEC terminology.
Because 'International Organization for Standardization' would have different acronyms in different languages (IOS in English, OIN in French), our founders decided to give it the short form ISO. ISO is derived from the Greek word isos (ίσος, meaning "equal"). Whatever the country, whatever the language, the short form of our name is always ...
The first known practical sensitometer, which allowed measurements of the speed of photographic materials, was invented by the Polish engineer Leon Warnerke [3] – pseudonym of Władysław Małachowski (1837–1900) – in 1880, among the achievements for which he was awarded the Progress Medal of the Photographic Society of Great Britain in 1882.

TAv: Some Pentax cameras such as Pentax K-50 has this mode for rapidly changing lights by using the widest aperture and the lowest ISO of continuously changing ISO between 1,000 and 3,200. [1] [2] The range of continuously changing ISO is dependent on the camera manufacture. Other manufacturers may provide this functionality through an ...
In the US, size names are often denoted with a code of the format nR, where the number n represents the length of the shorter edge in inches. In the normal series, the long edge is the length of the short edge plus 2 inches (10 in or less) or 3 inches (11 in and above).
