Whoa... Wow... This one had me taken aback. Did you use some kind of filter or color editing in photoshop or did the purple in the clouds come out that way in the raw picture? Either way that's stunning and it's awesome how some of the mountains are lit up as well. It almost looks like a sunset picture there's so much detail and color. Very impressive! Great capture. This is one of my favorite ones so far.
yes, that was the last shot, the sky was turning blue and the high clouds were showing the first light up there above 20,000 feet. the long exposures bring out more color. Thanks a lot.
