Just a simple photo manipulation I recently did. I took the original photo while visiting Maui last September. It's taken atop the Haleakala Volcano, at about 10,000 ft. It's was 5:00 am, just moments before the sun came up, and about 8˚Celsius... after going through some photos, I thought this one would make a great wallpaper. I tweaked the color, and of course added the stars, in Photoshop.
Just the one size, 2560x1600. Alter as needed for your resolution, and please don't use commercially, or distribute without permission.
