The picture shows an ASA/DIN conversion in a 1952 photography book [70] in which 21/10° DIN was converted to ASA 80 instead of ASA 100. Some classic camera's exposure guides show the old conversion as they were valid at the time of production, for example the exposure guide of the classic camera Tessina (since 1957), where 21/10° DIN is ...
Ultra high speed (for its time) panchromatic film. Although rated at ASA 640 / 29 DIN, best results were obtained at ASA 2000 / 34 DIN, very similar to how Delta 3200 film is officially rated at ASA 1000 / 31 DIN but is usually shot at ASA 3200 / 36 DIN.

An elaborated form of the sunny 16 rule is to set shutter speed nearest to the reciprocal of the ISO film speed / setting and f-number according to this table: [3] [4] Tessina with exposure guide plate from the 1960s. At that time, DIN 21 was equivalent to ASA 80. After 1983, DIN 21 was ASA 100. [5]
Film speed describes a film's threshold sensitivity to light. The international standard for rating film speed is the ISO scale, which combines both the ASA speed and the DIN speed in the format ASA/DIN. Using ISO convention film with an ASA speed of 400 would be labeled 400/27°. [29]
The ASA (as for American Standards Association) photographic exposure system, originally defined in ASA Z38.2.1 (since 1943) and ASA PH2.5 (since 1954), together with the DIN system (DIN 4512 since 1934), became the basis for the ISO system (since 1974), currently used worldwide (ISO 6, ISO 2240, ISO 5800, ISO 12232).
The camera's top plate has the manually set frame counter, the shutter release, the film rewind knob with film reminder dial, the exposure needle window, meter adjustment knob with EV and ASA/DIN scales, the film (advance) release button, the frame (counter) advance slider, and the accessory shoe. The bottom plate contains the tripod socket ...

UCUM is used by different organizations like IEEE, and standards like DICOM, LOINC, HL7, and ISO 11240:2012. [ 2 ] The code set includes all units defined in ISO 1000 , ISO 2955-1983 , [ 3 ] [ a ] ANSI X3.50-1986 , [ 4 ] [ b ] HL7 and ENV 12435 , and explicitly and verifiably addresses the naming conflicts and ambiguities in those standards to ...
