I'm glad the lighting was mentioned, as it was a major part of creating this image and what I strived for. So that makes me fee it was all worth it in the end. For background....
They were positioned under the overhang of an old western street facade. The sun was high and behind them, so there were in total shade. I wanted a late afternoon sun scraping across the desert feel, so I had to create that myself. I used nothing more than a large silver California Sun Bounce reflector. Positioning it just right to get the subtle but important light was important.
My assistant was about 150 feet off in the distance from the models. Any closer and it was over powering, any further and the lighting effect started to diminish. I had the assistant move toward the rear fo the models as well to get those shafts of light on Olga behind Josh. I exposed for the ambient, which was about 2/3rd of a stop less than the reflected light. Most of the fill for the ambient came from the sun beating down on the dirst in front of them, and was reflected back up to them. That allowed to me to forego a reflector on the ground to keep light under their chins, etc.
Thanks for the compliments. Its one of my favorites. I'll post a few more from the same series here, or in a new thread.
