Ok, kind of a noob when it comes to low light photography. I was at a game a few nights ago. It was in an indoor arena. The lighting wasn't that great, and when I was taking the shots, most came out a bit blurry and unclear. The flash obviously won't help, since the subjects are too far away. What is the technique behind a good low-light picture? I have a Canon S3 IS, just for reference. Thanks.
