This is the best photo I've seen you post here, by a landslide. The B&W conversion is impeccable, wide all the tones in the range seemingly there. There is maybe a bit too much contrast, but that's a matter of taste. The bright whites and dark blacks add a lot of drama to the scene. I'm not even sure what's going on in the picture, but I can't take my eyes off of it. Great stuff!
I'm nominating it for Photo of the Month.
