John,
You continue to spark my own imagination! I would never have thought of taking a photo like your last #1 and converting it to black and white. I like the result. Makes me think of one of my own that I'll try it on.
All 4 of these last ones are wonderful but I think I like #s 3 and 4 best because of the motion inherent in the sweeping color.
Is your forest really on fire? Or was that just a comment on the way #4 turned out, which, either way, is spectacular.
