Sorry if this is the wrong spot. Mods please move it if it is so. The situtation. I will be going up into the michigan wilderness in about a week and taking a train ride to some place. I thing the train is a steam engine and i want to get some grainy moody shots of it. I have used Ilford Delta 3200 ISO film before and i develope myself. However, I want more grain then that and my question is how far can i push this film? 6400? 12,800? That being said, i dont want to end up with point a lisim like pictures secondly, other then correcting for exposure problems, what sort of effects does pulling film have?
