After having an old Weston light meter donated to my photographic equipment, I needed to be able to be able to convert ASA information to Weston numbers. It would appear that this is less and less of a necessity, and there aren’t very many resources left to do so.
I posted this table a while ago, and it seems to be a fairly popular destination for wayward Googler’s, so I’m moving it to a new (and better) location.
