You say you were unsure whether to keep this in color. That made me try to see what it looks like in black and white. I did it via a channel-mixer layer but couldn't get it contrasty enough to be interesting, so I added a curves layer as well. Looked OK. Turned off the channel-mixer layer and now had a curves adjusted color image that was really cool! Try it and see for yourself: Two points on the RGB-curve: Input/Ouput=77/24 and 198/223. --Olaf.dk
