Does anyone know the formula for converting an aerographic ISO to pictorial ISO? I have bought a roll of that Plus x from Ed on ebay and it is labeled ISO 125. It doesn't give a aerographic designation but the Kodak website lists the 2402 film as ISO A 200. If there isn't a designation on the label would I be safe to assume it is equivalent 125 pictorial?
I have an older roll as well that a friend gave me and it has the designation EAFS 200. I need to know the pictorial speed so I can begin testing it. By the way, Mr.Foto was great to deal with.
