Holy cow, Rick! A sky like that would scare me out of town for at least long enough to reassure myself that the end of the world didn't happen while I was on the run.
As you've probably guessed, Glenn, it's been tweaked a little. Not much, though. We get some interesting looking skies here sometimes.
This is beautiful! i've seen real skies like this on occasion! here's a phone picture from a couple of years ago in Alabama. and it's natural color. thanks! sp
