Hello All, Got some friends that coach High School Wrestling and asked if I would take some pictures, wich i gladly agreed too. Off the top of my head there are some issues to overcome and workaround. These wrestling tournaments are held indoors at the school gym's. I shoot with a Canon 40d, the fastest zoom i have is a 2.8, i do have a 580 flashhead but i dont know if i'll be allowed to use it. Theres alot of action in there so the shot will have to be relatively fast to avoid the blurrs. Any Tips N Tricks to for this shoot besides raising the ISO all the way up?
