Do I HAVE to use a flash? I regularly shoot random pictures at the local skatepark beside my house and almots everyone wears dark colored t-shirts. background either being the sky or some really reflective white cement on a bright and sunny day. being a very fast paced sport, I get about a 20second notification (MAX) before some guy does a trick for me so I don't have much time to setup anything. With the canon 10D built in flash, the max shutter speed is WAY too slow to get a nice sharp image, plus the fact that this flash is so harsh that it makes the picture worse. I want the object to be nice and bright without the background being crazy over exposed. how how how? I would like to get a 'real' flash (ex 420 or the likes) but me no moneys .
