When I did this photo shoot with Krysia I took along an empty photo frame, with the intention to produce a variety of different "fills" to the frame, this double exposure idea being one of them. As I shot her nude and again in underwear it was important that both her and me stood in exactly the same positions for each shot and that her pose was identical for both, which took some mental planning as well as lots of "tweaking" of her pose with arm position etc. She did not really get what I was trying to achieve but stood as still as possible and accommodated me when asking her to move half an inch here and there. Patience pays off.
