The Sept-Oct issue of Photo Technique has a short article on using
Hugin's panini-general projection. Web abstract at
http://www.phototechmag.com/index.php/septemberoctober-2011/thomas-k-sharpless.
I guess subscribers can read the whole thing online; but hey, buy a
printed copy and support local business.
As the author of both the s/w and the article, I shall refrain from
comment. But my wife thinks it looks terrific.
Best, Tom
