I wasn't sure if it's up to me to find the settings, which it probably is...but tonight I'm going to my old school's hockey game to take pictures. The arena is bright, but a little dark at the same time. I've never shot inside a hockey rink, and I was just wondering if anyone had some preset settings they use. Also, I'm using 400speed film...any good for that kind of thing? I have 100...which is better?
