Lots of middle of road, even headed answers and voting here. I love grain. It's one of the reasons I shoot film. Also, the only reason to shoot film is to shoot black and white film (gospel according to Shawn). I like the raw and dirty look. I like the painstakingly charcoal and soot look. (I like the well heeled aesthetics of slop). I like to look and feel as though I could see the world and it's people made of subatomic grain particles, each savagely fighting the other for time and space. I am so not into two dimensional curation of the outer world; the outer world is my interior, and in my out there, there is GRAIN.
Grain of this order is managed by contrast, which is, in turn, managed by, well, every single other photographic factor.
