Old thread is old. But anyways, I've shot a few tournaments and learned several lessons from both experience and talking to players. I played Xball for years, and know the feeling of wanting all the pictures. But a few things to keep in mind...
1) Framing is key. Its often hard through a mask, but try your best not to chop limbs if your going for a full body shot. Many players like the full body shot. If not, go for a tighter crop and get a close up of gunning, reloading, etc.
2) Knowing the game is also a key factor. It often helps to know the moves that most people are going to make. The snake is a crucial bunker, and most people will dive in. Position yourself in a spot that allows for a clean dive shot.
3) While to the average person, a shot of a player running may appear boring. Players love pictures of a bump for big move. Break out pictures make great shots, and teams love them. Not ever shot has to have a ball breaking, but they make for better public pictures for the general population.
4) Never shoot down on players. Always get on their level and shoot. If you watch the big PSP/NPPL tournaments the photographers can often be seen laying down


Didn't mean to thread jack there, just wanted to show some examples...
