Thanks all! The lighting is a mix of on and off camera flash. The first and last was a Ranger EX setup just slightly behind and to the left of camera. (We do sometimes boom it, depending on the conditions.)
The remainder (exept for the ceremony and the sillouett-sp?) were taken using our weird backwards flash way of shooting. Basically, I turn my 580EX2 flash around absolutely backwards so that it sits on my head. You have to be very close to shoot like this however. I will also warn you that this way of shooting can be a "flash killer". My flashes get so hot sometimes that they turn themselves off. I carry about 5 of them though, so I just go to the next one. I do this though, because I really like the look of it.
I can't recall if we used flash on the ceremony, but most likely, we didn't. (It's frowned on here in the South).
Anyhoo, I hope that helps!
Thanks again for all the kind comments.
