i shot a level panorama on a pano base and had it automatically stitch. it came back with a wavy horizon. several other programs i tried have done that. i own about a dozen panorama stitching programs and once Autopano Pro came out, i stopped using the rest. PTGui never went onto my bought list. every time i tried it, there was something that was annoying about it that my main programs did better.
Autopano Pro is the only program i have used where i don't tell it anything except which images belong in a panorama and it gets it right for a very large fraction of my stitches. by changing how many control points it automatically uses and how hard it looks for control point matches, i can stitch every panorama i have tried without ever editing control points manually like i have had to do with every other program at some point.
