Thanks for the info guys! I will keep most of the editing simple with a few photos done both simple and with a little more time spent on them. I will try your suggested settings, Mark and see how it goes from there! I just ordered an omni for the 430ex II yesterday since I only had one for the 580.
When we were at the venue, the guy only had yellow lights on and said the red will be much more intense! I could see yellow going across only the upper half of the gtb's face and it did give me a sense of what challenges lie ahead! It will be interesting ...red bridemaids dresses with red lights! I just hope the brides face isn't red when she sees the photos!
