This reflection of the sky was shot in Chicago, at the sculpture known as the "Cloud Gate" (but which everyone just calls "The Bean"). It's a highly reflective polished chrome (?) sculpture. If you look in my photo stream at the photo just before this one, you can see the whole sculpture.
I think the streaks in the lower right are dirt on the surface of the sculpture from where people touched it. I wasn't sure if I should leave them in or not - but I think without them, this looks like just a photoshop effect, when, in fact, it's real life.
I've noticed a lot of hits on this photo lately. If you don't mind, can you drop me a note and tell me where you found this image? Thanks!
