Thanks to Chris and Jeremy for your comments. The chapel is very small and in a remote part of Argyll in the West of Scotland. The only light comes through some windows in the walls and also in the roof. The camera was hand-held and I had to steady myself against a wall to avoid camera shake. The 'woman' in shot - is actually my wife !! I will post another shot of the chapel from outside just so you can see how small it is and the beautiful location it is in.
