Ah, well, I like real light/light conditions, or as real as photography can get, and fooling with the sky color would usually just annoy me. I can imagine some photos that are all about playing with that, and then I'd possibly be interested.
I think I got a free 30 day trial of Photoshop Elements and I love it -- and I say this after being a Photoshop 7 user for years. Maybe because I was trained in film photography and still shoot that way but I used very, very few of the tools available in the expensive Photoshop programs.
