Ken Rockwell on Amazon's rather controversial new patent related to photography:

Amazon was just granted US patent 8,676,045 for a very clever and particular way to arrange a raised Plexiglas platform, lights and backdrop to give instant in-camera images with a 100% white background and a slight reflection below the subject, all with no postprocessing (like Photoshop) needed to make the platform blend into the background.

Clever, and it's funny to see how many other sites reported this wrong.
