Just returned from a two week business trip that, for the first time, got me around the world in a single trip: Chicago, Tokyo, Seoul, Daejon, Singapore, London, Berlin, London, and back to Chicago. It was a tight schedule during the local work days plus a second work day at night doing email and conference calls with the US. But I got out a little and here are some of what I saw ...
This is part of the roof structure in the Sony Center in Berlin. Probably the most photographed location in the center, I still like how the blue sky is a nice backdrop for the piece that holds the entire roof.
Picture details: Aperture: f9, shutter: 1/320s, focal length: 70mm, no flash, no tripod.
