Found some rolls of Fujifilm 35 mm color negative film. The only identifying marks are Fuji, Safety, and the numbers "325", "F-II 636", and "F-II 373". My records show they are from the early 1980s but not what type of film or the ASA.
Is the F-II film always ASA 400? Just curious if the numbers mean anything:
I am scanning them with a Plustek 7600Ai using SilverFast Ai Studio. SilverFast uses the ASA to adjust the image. Makes a big difference since I don't have to make several guesses and try to adjust on my own.
I have been able to find this information for Kodak films but so far no luck with Fujifilm.
Back then about the only film speed choices were 100 or 400, so it would only take you two scans of each to find the best results. If the negs are worth scanning they'd be worth taking, what, ten minutes to find out?
Where are you getting these numbers, from the edgeprint?
Yes, they are printed just outside the perforations. You are correct about few choices in 1980 -- I suspect that "325" is probably ASA 100. There is extensive documentation on the Kodak numbers (like: 5035 = Kodacolor II, ASA 125). Why not for Fujifilm?
