I'm photographing division 1 men's lacrosse tomorrow, and I have never photographed lacrosse before. I'd like tips for photographing the game, and any important information that I should know about NCAA rules for lacrosse photography such as whether photographers are allowed to stand or have to kneel, and where we are allowed. Also, I'm a bit concerned about safety. Are photographers allowed to wear a helmet in case the ball hits you in the head? Does anyone ever wear one (no, I am not kidding)? Thanks.
