I headed crosstown the other day on a mission to Barnes & Nobel. The day was brilliant, and the sun was just about overhead - not normally a great time for photos.
But when I saw the pattern of shadows on the stairs, I thought it might make a good background for some people in an HCB-like setting. I took several as people came and went - this is my favorite of the bunch.
