Lens Shift Panorama
This is a 2-frame panorama stitched together in Photoshop CS4. One frame was shot with the lens fully shifted in one direction and the other was shot with the lens fully shifted in the opposite direction. One frame was simply laid over the top of the other - no correction was needed.
