The implied value (1/3.125) for the speed scaling constant given in the Exif 2.2 specification ("Exif 2.2"; JEITA 2002) differs slightly from the APEX value of / (0.2973); with the Exif value, an ISO arithmetic film speed of 100 corresponds exactly to a speed value [3] of 5.
"Exposure value" indicates combinations of camera settings rather than the luminous exposure (aka photometric exposure), which is given by (Ray 2000, 310) =, where H is the luminous/photometric exposure (lux seconds) E is the image-plane illuminance (lux or lumens/m²) t is the exposure time ("shutter speed") (seconds)
For some while, ASA grades were also printed on film boxes, and they saw life in the form of the APEX speed value S v (without degree symbol) as well. ASA PH2.5-1960 was revised as ANSI PH2.5-1979, without the logarithmic speeds, and later replaced by NAPM IT2.5–1986 of the National Association of Photographic Manufacturers, which represented ...
