As seen from the Gatlinburg bypass.
Well I learned something today about using circular polarizers to make a paonoramic. DON'T.
As you can see the polarizer really works. And you can see my lazyness in not blending the edges after Canon's Photostich program. Normally I have easy success with Photostitch. But since the polarizer worked to darken the blue sky and saturate the vegetation it is easy to see the drop off on either side of the center frame. The center frame was the one closest to 90 degrees from the sun. The orientation that a polarizer works best from.
