Hugin
Hugin is a simple little program that will meet a specific need of many shutterbugs. It allows one to create panoramic photos just like those taken by the pros.
The program has a series of useful functions. For example, you can put different photos together to create a panoramic effect or you can literally "stretch" a photo though in the second case, results may be less than perfect. Fortunately, it's easy to use Hugin even for non-experts. A complete guide is available along with a tutorial that should help you make the most of the software.
The download version of Hugin is compatible with Windows 2000/ME/XP and Windows Vista. If you go to this page, however, you'll find versions for Windows 95/98, Mac and Linux.
