This shot was complete natural light. It was a serious challenge, but I am rather satisfied with the results. the only photoshopping was the 8X10 crop requested by the customer, the sepia toning, and the scratches and stains. the image itself is untweaked in terms of exposure, contrast etc.
I abhor artificial lighting. at most I might use a scrim, and maybe a single speedlight...maybe, but probably not. I find that working with only the light which nature provides is a demanding and rewarding philosophy. I don't always get it right, but when I do, the results are good.
