http://www.flickr.com/photos/phloodpants/sets/72157626086079045/ I set the camera to ISO 3200 and had Richard Photo Lab push it three stops. I was pretty amazed at the results! It seems that you really need to avoid underexposure though, or it gets foggy and grainy. Any suggestions on improvement? I am shooting a roll right now at 2400, and will still ask them to push three. Does that make sense if I am trying to keep grain down?
