Bruce Barnbaum (I think) contends that any B&W film such as Tri-X can actually record up to an 18 EV range of film presumably with a lot of this range compressed into the toe and shoulder.(posted 8607 days ago)Presumably a master printer like Bruce can actually recover this information from toes & shoulders, but for rank tyros like me, chromogenic film and Tri-x do allow for some slop, up to about 7-8 stops, so I can be pretty casual about exposure for say low contrast street scenes on rainy days. Seems like XP2 super allows for more slop than Tri-x, but it ends up being harder to print.
