In a previous Ask TUAW
we covered a few of the panoramic photo stitching options available for the Mac. Now another tool for doing this has come to my attention and is probably worth a look for anyone interested in making panoramic pictures from multiple photos. Hugin
is a cross-platform GUI for the Panorama Tools
open source project created by Professor Helmut Dersch. It has many detailed options for stitching photos together exactly the way you want it done. As such it's probably not the easiest panorama tool to use, but by the same token it looks quite powerful. You may want to check out some of the tutorials
available to get a sense of what it can do.
Hugin is a free download
