A while back I found on these forums (or APUG) a nifty calculation for reciprocity for FP4 and HP5 (same calculation) that made the use of a table unnecessary, and is more specific. Does anybody have one for D100 and D400? I have one for Tmax 400- would D400 be the same, being a tabular grained film? I thought speed would enter the equation, but apparently not for FP4/HP5.
