I just installed and played a little bit with this nice iPhone app, Autostitch, which is receiving excellent reviews from the blogosphere. I was quite impressed by the quality of the alignment and by the resulting panorama.
Yesterday I did a test with this sequence of images:
The iPhone 3G lens is quite wide-angled, so Autostitch also has to correct the lens distortion: there is also the nasty detail of the light pole in the two central images. Below the result of Autostitch:
I was quite happy with it, the lens correction and image blending are good (even if the light pole is presenting a problem). Nevertheless, I launched Photoshop CS4 and made the following panorama using its photomerge function:
This is so better than Autostitch: the central pole is perfect, and exposure is also more pleasant. Even more, Photoshop panorama is 4389 x 1351, while Autostitch is 2478 x 716: where are my pixels, Autostitch? I then tried the Autostitch Windows application (available for free here):
Result is closer to Photoshop, at least in size (4988 x 1435) but the pole is still an issue. At the end, you can always trust good ol’ Photoshop!
