Not a particularly stunning image on merits of composition and such, but more a piece of technical mastery I'm proud of. Very rarely do I ever shoot my 12mm f/2.0 at anything below f/8.0, I just like the crisp sharpness it provides. But this image was taken at night in a building that was nearly pitch black. The camera saw more in its 60 second exposure at f/2.0 than I saw with my own eyes. Was pretty amazing to look at this and see just what I was missing in the dark.
