Here is my custom bracket made by me
It's combo of 580EXII on top + 430EX on the side + Battery pack for 580EXII and + PW .
What I do is ...I set my Alien Bees (2) where I need for group shot or family shot at the reception then turn PW on ,turn off 580 and 430 .
580 and 430 use only when I walk around for candid shot and then I turn off PW .The flash will spread out even to the photo ,the problem is if I only use 1 flash 580 the horizontal is ok ,but the vertical shot is not good enough ,the flash will not contribute even around the photo .So now when I add another flash on the side ,that would be enough flash for vertical shot .
That is so nice about 580EXII is that trigger the 430 .
I used my 5D with Metz to take the bracket sample ,so I don't have any photo of that set up yet ,I'll post the photo by this weekend .
