Evening all, I went down to our local camera store this afternoon to pick up a few things. I'm getting ready for a road trip as I desperately need to get out of town for a few days. I asked for 4 rolls of my normal b&w film, these days HP-5. When I got home I discovered they had put Delta 100 in the bag. This is a film I've never gotten around to using in the past and my question is this: Is Delta 100 processed with the same method as HP-5, Tri-X and so on or is it a C-41 process film? I know I could open up a box and find out but would rather not in case I need to return it. The slower speed is not an issue but I do all my own b&w work and want to be able to print it in an enlarger and not have it machine printed. Is there anything unusual about this film? Thanks. Rick H.
