Even though I have been shooting on and off for many years I never really used a flash. Now I was toying with the idea of using flashes for some fill lighting for some out door shots. Here’s the types of scenes I have in mind. First might be a sunset off a dock at dusk and I would want to softly light the dock and not effect the sky. The second would be a more dramatic night scene where I would want to shoot a quarry and light up some of the machinery against a black sky. Right now I have a Canon 30D and was considering a 580Ex and then a 430ex as a slave. I would want to mount them both off the camera so what else would I need besides the 2 flashes and 2 tripods to make this work? Also what kind of diffusers (if any) work well? Thanks for any help.
