Original, as shot, in JPG format.
Processed with Perfect Photo Suite 6, using masks and layers to darken sky and apply "cracked paint" effect to wall. (The school doesn't really look like that!)
Same as above, just "auto-toned" in Lightroom.
Converted to "B&W High Contrast" in Lightroom.
"Selenium-toned" in Lightroom.
I can't make up my mind about which I like the best. It's either the high contrast B&W version, or the one that's selenium-toned.
