There is a local tournament that I'm going to be shooting on Friday and I'm looking for ideas. It's a fund raiser, there should be like 30 golfers there. It starts at 11am and goes till it finishes. I will bring my 40D, my 28-135IS, and my 10-22. I will have a tripod, anything else I should bring? I have a cheap manual external flash that I will be bringing along as well just to get some fill light, but it will be on camera. Anybody have any example pics or suggestions?
