I'm attending a graduation ceremony shortly and would like to know hot to get the best chance of success. I'm guessing the will generally be low so I'm assuming wide open + high . Do you think that will be fast enough. I don't have a speedlite, just the pop-up on the 450D. I have the twin kit plus a 50mm1.8 which I am really enjoying lately and guessed I would use for the ceremony.
Any advice greatly appreciated.
