We did the Chicago Skyscrapers tour yesterday morning and it was so interesting. Sadly we were not allowed into the Rookery to see the floating staircase but we were able to go into the lobby. WOW what a fabulous building! This is with my fisheye lens. I just love that lens especially here inside some of the buildings - great effects!!
Oh, your fisheye works a treat on this wonderful space. It even caught my hubby, at the corner! :) We were all open-mouthed at the beauty of this space. Nicely captured.
