It's hard to give useful input, unless I know what you're after. Are you creating a piece of art? If so, what's wrong with even-ing out the sky tone?
I shot for a couple of days at White Pocket in the fall of 2007 -- a truly WONDERFUL place. Not a week goes by but what I think of it. It's the most remote place that I've ever been -- two hours from any paved road (by vehicle). God knows how long it would take to hike out of White Pocket -- days and days!
If you care to discuss your experience at White Pocket, email me. I'd love to share .... and show you some of my images. Thus far, I've converted them to black and white.
