I love your work, what a great place to shoot. Let me suggest shooting in "Manual" when shooting a Panorama. You might want to bracket or try a test shot of each end and the center. Look for under and over exposures in the histogram and then shoot all angles using the same shutter and aperture settings. That will stop the light / dark gradation in your panos. I miss the Nikon forum, I was heckled there and when I fought back, I was booted off. Good lock and keep up the great work, TRY my suggestion. maustin@fuse.net
