Yeah, grain as in noise. Digital really does handle noise a lot better than film now, film used to have really noticeable noise starting from 800 up I believe. But I never really use more than 400 film, since I'm just starting out anyway. I use the cheapo Fuji Film stuff. I might want to grab a roll of black and white though.
This is all dependant on film format, film type, developer choice, and what ASA you expose your film at.
cheap budget 400 color neg is grainy as hell, while a good film such as Kodak Portra 400NC is far less so. Even Portra 800 has pretty subtle grain. Once you hit medium format, grain is much less of a factor, and if you happen to use 4x5, 8x10, or larger, it's not even part of the equation. 400 speed 8x10 has more detail than cutting edge digital medium format backs -wish- they had. I'm not even going to bring up the whackos who use 11x14, 7x17, or 20x24".
But in the words of our good friend Henri Cartier-Bresson, sharpness is a bourgeois concept anyway. So is grain. People who ridicule a great photo because it's visibly grainy are probably not worth half their weight in salt as photographers anyhow.
