These images were shot on a hot, hot day, over 100 degrees, with the mid-day sun making things extra challenging.  We found a good shady spot under some trees and added two remote NIKON SB900 speedlights for fill-light.  Viewing the images or histogram on the camera back during the shoot was next to impossible in the bright conditions so I had to trust my light-meter and bracketed some of the flash settings for insurance.
