This is one of the beautiful stairways leading into Chicago's Union Station's great hall. Amazing!
How I took this shot:
This handheld vertorama was stitched from 4 HDR sequences each containing 3 shots ( -2ev, 0ev, +1ev). I would have used my tripod but one of the security guards was already watching me, I didn't want to give her a pretense to kick me out. It's happened to me more than a few times before.
