I shot this whilst with one of my photography students. The assignment: lines and curves. And we were shooting just in black and white. There is a superb spot on the top floor of this amazing building where you can get a great wide-angle shot but also capture a perfect reflection of what is above you.
This was a five-shot bracketed HDR, shot in the monochrome picture control mode on my Nikon DSLR. Merged in Photomatix.
