I just got back some Fuji 800 color print film (purchased at walmart) and the results were terribly grainy. I had used this film before and didn't notice the grain being objectionable on 4x6 prints, but this roll, since I viewed it on a computer screen, was terrible. Maybe it was expired. But anyway, what are some fast color films, either in C41 or E6? I understand there is Provia 400 and I'll probably shoot more of that, but are there good fast (or pushable) print films out there? How's the grain on Fuji's slower print films (such as superia 200)?
