Wow, KT. Compared to yesterday's mill shot this almost appears to be abstract art. Vey different textures and contrast. Now I'm going to be the one to ask you to post the color photo please. Thanks!
The grays give a feeling of age. Nice! My only quibble is the bright "box" above and to the left of the roof. A little distracting. If it was being printed with an enlarger, I'd suggest burning in that area...
