I shot this one in portrait format in order to preserve the vertical lines, and cropped it to a square format to suppress the less interesting part. Tripoded of course, but suprisingly I used only one exposure time (no HDR) as the balance between the sky and the lamps was good at this hour. Minor corrections under Lightroom.
Lens: Sigma 10-20 f/4-5.6 (click to see all my photos with this lens)
