Thanks for that everyone. Peter - they were just the people in front of me in the queue. The sun was quite low in the sky but it was a beautifully clear, but cold day and the people were only a metre or so away from the wall, so the shadows came out quite sharply.
Thanks,
Chris
Very nice! Enjoyed seeing these. I especially like the first one - more figures, which make the capture even more impressive, and what seems like a door at the end gives the whole scene a bit of perspective.
