I will be shooting a few amature snow boarders. These kids are my friends and I'm more or less looking for something to shoot during the winter to keep from leaving my camera down for too long, as i predict may happen. I enjoyed taking pictures of skateboarders and am going to try snow boarding. Is there any recommendations you guys have for shooting and exposing in these conditions? I've gotten him to pick out of magazines all the shots he like, so I can do my best to give him something he likes, although it's unpaid and just for me to have something to do.
