One of the first shots with my new 17-40L...wonderful lens. One of the many buildings in the Health Sciences complex at the University of Washington. Although the sky had a very nice blue color, I think the B&W version looks best.

Great pattern here.
Would have worked even more by correcting the perspective a bit IMHO.
But it looks great already!

i love that moody sky and dark tones of the building -- great job!
