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).
The ISO standard for film speed only applies to visible light, so visual-spectrum light meters are nearly useless. Film manufacturers can supply suggested equivalent film speeds under different conditions, and recommend heavy bracketing (e.g., "with a certain filter, assume ISO 25 under daylight and ISO 64 under tungsten lighting"). This allows ...
In 1991, it was split into DIN 476-1 for the A and B formats and 476-2 for the C series. The former has been withdrawn in 2002 in favour of adopting the international standard as DIN EN ISO 216, but part 2 has been retained and was last updated in 2008.

[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 allows for a better image in high light conditions providing a smoother image and low grain. Meanwhile black & white films are sold with ...
