Dome of Cologne
Color correction was quite difficult here, because of the lot of different light sources. Setting whitebalance manually to fluorescent tube produces this composition.
This is a normal shot without any DRI. As with most of my night-images it was recorded in RAW format to decide later about whitebalance and have more freedom for contrast and color adjustments. This is also a cut of a large pano, which I only had done for resolution, a normal lens would give exactly the same framing.
