Oh and I often use the 10 years = 1 stop rule. So Example...

32ASA film that expired in 1983 would be shot at EI8.

If the film can be verified frozen all that time I would half the number and do EI16.

Hope that helps. The above images were shot at EI3 but on paper should have been EI0.75! But my meter only went to 3ASA and I figured there's a sort of reciprocity factor that at some point a film won't lose speed as quickly as it ages.

I also think I might have shortened the developing time by a minute to get more contrast and less fog but maybe not.

I have 3 more of those reels so we shall see what the next one gives.
