All things being equal, I'd suggest following Kodak's suggestion to have the film processed in a C-41 lab. Kodak TCN400 is the "professional" grade, and Kodak B&W+ Select is the "consumer" film. I believe the B&W+ is optimized for printing truer grey tones in a c-41 lab. It all depends on the color chnnel the lab uses. I kind of prefer Ilford XP-2Super for its grey tones, 36 exposure rolls, and slightly lower film cost. Try the c-41. You might like it.(posted 8479 days ago)
