PTMac

Disclaimer: I'm a hobbyist with only the most rudimentary graphic editing skills.

Over much of the past year, I made QTVR panoramas with PTMac. My 6 horiztonal shots stitched wonderfully, but adding the zenith often caused errors with seams, in the triangle formed by the zenith shot and the first and last horizontal shots. Usually the error would be a small section off by 1-3 pixels. I'm working on acquiring the graphic editing skills to take care of such errors.
