It's interesting how tenacious some things are in photography. "ASA" - the American Standards Association is no more - it was replaced by "ANSI" - the American National Standards Institute", some time around 1970 - 1973 ~ 30 years ago, or so.
ANSI, itself is no more - everything went to ISO - not sure of the acronym, but something like "International Standards Organization" .. some time in the early '90's
Interesting - how we cling to "ASA". The only place I see it mentioned now is in reference to film speed. It is correctly, "ISO"... lest someone starting out become confused.
