Photographing trees with a vertical panorama

An interesting article on NPR on how National Geographic photographed a giant red-wood tree when there were no real clear lines of sight. Think vertical panorama.

Basically they set up a vertical pulley, and lowered the camera down, taking pictures as they went. The end result is 83-photos stitched together to form a large panorama of the entire tree. This from around 40 feet from the tree.
