[QUOTE=brucemuir;1449539]I always am GENEROUS with exposure with Foma films.
I rate Foma100 at 64 normally.
I try to never use a new film before I check how it behaves, and once I have things zeroed in I stay with it.
I used TMX and TMY for a decade exclusively with T-Max developer for this reason.
THat professor I bring up, told us to do a "real film speed" test for every camera/film combo we planned to use.
Extreem...yes. But surprises were fewer ... which is a good and bad thing too.
