Hi! I'm new to the forum. I have a lot to learn. I take sports pictures for local youth and high school teams.
I just purchased a Canon 580 EX II Speedlite but I don't understand how to set it up properly to get night time action shots. I have a Canon 5D, a 70-200 f/2.8 Lens and a 400 f/2.8 lens that I use for sports photography. I have been shooting without a flash but I am now required to shoot at ISO of 800 or less in order to turn in my shots. The field I'm shooting on is ridiculously dark (friday night football). I am learning as I go but I really need help understanding how the flash works. I have a Quantum Battery pack as well. I'm wondering how many shots I'll really get out of it during the game. I tend to take a lot of shots during the game.
Any help would be extremely appreciated. Thanks.
