Film for Underwater
Not a rangefinder question, sorry, but y'all are the most film-oriented group I'm a part of.
Most of the films I used to like seem to have vanished in the last, oh, 15 years.
I'm going to Hawaii later this month, and I'm going to be doing some shallow-water snorkeling with my Nikonos. So the question is, what film? It'll be shallow enough that 100 ISO may be fine, though I may want to have some higher ISO film as a backup.
So, what film? I tend to like the really saturated ones; Velvia seems an obvious choice, but Provia's also available -- and I really have no sense of how they're different, nor do I have a lot of time to figure that out. B&W isn't really an option for this as I want the color.
