This very day I was wishing for slower film.
I'm at the beach on vacation (holiday for our friends in the UK) in North Carolina, took my CrGraphic to a nice spot on the sound where my son (Ok, ok, "We") were doing some crabbing. The sun came out as I was setting up, and when I metered (Using TMax100), it told me f22 @500! Damn! My Graphex sutter doesn't go that fast!!! Oh, what I do for a nice, dense ND filter!!
It would have been nice to have a few sheets of PanF or something even slower.
Bagged the shot and got my Minolta 35mm out, instead. A bit of a let down...
