I shoot a lot of city street stuff at night and go with TMAX 3200 rated at 1600, as do two other guys I know shooting the same style of stuff. IMHO that seems to be the best compromise of film speed and image quality. Most exposures ( city streetlights and sidewalks ilumianted by stores) seem to fall right at 1/15th at f 2, maybe 1/30th if lucky. I would hate to lose that 2/3'rds - 1 full stop by shooting at ISO 800-1000. That little bit of film speed is a BIG deal when you are hanging on the edge of "handheld". I like 1/30th, 1/15th is ok in a pinch, but 1/8th scares me.(posted 9199 days ago)
