Here is a casual shot of the west face of the John Hancock Center in Chicago. I had no room to back up further, so this is as much of the building as I was able to get into the frame (focal length--24mm).
Some shots taken while on journey in Sao Paolo, Brazil, last year.
All with 5D3 and 24-105 f/4 L; all processed with Silver Effex
