Aside from utilizing some of the aforementioned "stand developing" techniques/developers, shadow detail is obtained primarily through the exposure, not development. So for determining my effective E.I. with a given film, I always want to know if I've acheived a threshold density in Zone I of at least .10 above FB+F. If I have then I'll also know what the E.I. is for that film. Truth be told, my "normal" E.I. for FP4+ is 25, ditto for J&C Classic 200, and 100-160 for HP5+. I've simply accepted the fact that when the Winter Olympics come to town in 2010, I won't be doing anything even remotely motor driven. ;-)
