Another one from my session this weekend (also taken on the Mamiya, with Kodak TMax 400, I believe this was f/8, 1/250). Here is a picture of the whole apparatus (isn’t it a hoot?) I’m getting the color roll back tonight, so there will be a few more next week.

I know I asked out of curiosity once, but where do you get your black and white film processed – cheaply? I tried that in the past and had to pay extra.
