Curves, Shadows and Bricks

This would be the back of the Canadian Museum of Civilization's [link] administration building, taken late at night.

My favorite parts of this shot are the shadows created by lights both on and off the building, by the cracks between bricks, and of course by those amazing curves.

As the emphasis is on shadows, the contrast has been slightly altered. Hope it's a good kind of alteration.

Full view please. Thanks!
