ONS6's night photography was on my mind when I took this -- at night but indoors. It's at ORD - Chicago's main airport and is part of a holiday display. On the other side of the fence is a row of Christmas trees that are reflected in the floor to ceiling windows that look out on the tarmac. Processed with Silver Efex low key, adjusted for contrast and brightness.
Night shot after arriving in Dallas is in my extras album: http://365project.org/taffy/the-also-ran-ph/2013-12-03
