When I saw this angle at the Ingapirca ruins site (outside of the city of Cuenca, Ecuador), I knew immediately that I had to do a shot of a frame inside of a frame. The place just called for it. The small window inside of the old priest room fits beautifully in the door frame. It was an overcast and dark morning and that helped to give the site an erie mood.
