This is a 30 shot pano of some tree in some garden you might have heard of.
I tried stitching these 30 shots together in Photoshop but it could not handle it.
In the end I had to enlist the help of Autopano by Kolor which handled it no problem.
I could probably print this at 16 feet and still have super sharp resolution. If I could open the file that is ;)
