ISO is valid in Collins, not in North America — 3 points
It depends on the list you play by. ISO is in Collins, used in the UK and most of the world, but it is not in the North American lists — so in a US or Canadian game an opponent can challenge it off the board. Worth 3 points. Words with Friends does not accept it either.

What does ISO mean in Scrabble?
noun
technical
A single camera's recorded footage, kept separate for later replay, especially in television sports coverage.
A television director calling for the iso wants the feed from one particular camera, isolated from the main broadcast mix, so that a single angle can be replayed cleanly after the action. The word is a short, clipped form of isolated used inside broadcasting and film production.
How ISO is used
Technical; used mainly in broadcasting and film production rather than everyday speech.
