My proposition is that iso should be kept as low as possible as a matter of best practice.
Always. Absolutely always. That's the first thing that should always be taught in class. Camera ads, Kodak film ads (in the past), etc., made it sound like high ISO was somehow better. The best images and the best practice for taking images is always to shoot at the lowest possible ISO that can be used for the given subject and conditions.
Sometimes people mistake this for meaning "try to shoot volleyball at 1/125th to improve image quality." Sometimes the lowest possible ISO is extremely high for some subjects.
But that is the golden rule, briansquibb, and you couldn't have said it better.
