It seems that black and white film is just a little harder to find than color film. Or at least my amazon search wasn’t instantly successful. Anyways, Kodak T-Max and Tri-X seem to be two of the most popular. And it’s a little difficult to find just how they differ on a user’s level. The most useful comparison I found was here, and after looking at that, I think I might have a preference for T-Max, but I’m going to get a couple of rolls of each and see how it plays out.
