>>4060011I always push mine between 1600 and 6400 ISO.
6400 is mostly for when I'm going to be shooting with a minimum aperture of 2.8, but it looks great processed in D-76
3200 is amazing when you need light, it introduces haze around harsh light sources, and the contrast is really striking.
1600 is the best all around for me, strong contrast, manageable yet noticeable grain, super-versatile, I love it.
