John, a further factor: the points of the umbrellas were just about boob height, when she was standing up straight. This allowed the light to fill in under the hat without hat shadows that would have resulted from more top down lighting.
The model was standing in front of black velvet, and I was using two 580EX speedlites on each side of her, slightly forward. The lights were flashing through cream-white umbrellas pointed directly at her just beyond the crop you see with the newspaper shot.
I have a wireless light trigger mounted on my 5D camera that allows me to take advantage of ETTL. For convenience, I often shoot in the "P" mode, whatever that means ;-)
Also from my camera I can thumb the strength of each light back and forth with an "A-B slider" as I shoot. That's why you will see light dominant from one side to the other throughout this series. Sometimes it's balanced equally in the middle.
I usually have my ISO set at 200 for this lighting setup just to help out the lights a little and it allows me to move faster, hand held. For me, the flow and feel of a fun photo shoot is more important than a static lighting setup, so I give my priority to that -- quick and easy, with fun results being the objective.
