Thanks for your comments. This is one of my favorite places in Death Valley - the Racetrack dry lake playa. One of the most peaceful places I've visited.
Yeah, I see the faint line - it's actually there in the full-rez pano (3-4 frames joined IIRC), but accentuated by sharpening and, ahem, the 200K file size limit ;-) - Paul
What beautiful clouds! Very smart to make a panorama. How do you suppose you got a white line along the edge of the mountains? Too much sharpening, perhaps? ~Sharon
