Third shot of a June megastorm on the Panhandle Plains. Actually, I was in NE New Mexico, but right near the border of the Texas and Oklahoma pan handles - essentially, out in the middle of no where.
Yes, the foreground is a little "jagged". Lighting was very, very low relative to intense background in sky, and I wanted to cram as much texture in the highs and lows as possible. I used some of the new features in CS3 to bring up the foreground, add in some texturing, without increasing apparent noise too much.
