When you go taking pictures expect to get shot there are too many people who do not have any trigger control. Every time I take pictures I come out with welts all over my body, I understand that it is going to happen and is the price I am willing to pay to get good action pictures for all of us.
There is only a couple of us that will go out and take those pictures during a game the only thing we ask is to just take 1 second to see who you are shooting at, you should be doing this any way too avoid shooting your own teamates. I don't mind getting shot but it really sucks when you get it up close so just take a second before you fire your target is not that quick to get out of your kill zone.
