Panorama Perfect Lite
Match up photos using nodes on the blending area of each photo with no distortion when joining.
Pros & Cons:
Panorama Perfect Lite is the freeware version of a commercial product, but the only difference I can see is a limitation on the size of the panorama picture it can produce. However, this should not be a constraint for most users.
The strength of this software is its ability to match up photos taken without a tripod. Using nodes on the blending area of each photo, you can match each structure (tree, building etc.) to ensure that there is no distortion when joining.
Although more complex, this process allows a better stitch without the bending and distortion you sometimes get with AutoStitch. This difference will not be important to casual photographers, but more serious users will consider the effort worthwhile.
Currently the product is not available for download from the developer but you can still obtain it via a third party website from the "Get It" link provided above.
