Autostitch is essentially a graduate student project. And their old website,, has vanished, so no support unless you can find it in a forum. Autostitch's Help has only an "about" screen. There may be some combination of spells in the arcane settings of Autostitch that will get me decent output from Autostitch, but I haven't found it. Scaling up the output from the larger JPG's resulted in an "Out of Memory" error. The default resolution is too small to view, and when the size is scaled up from 2% to 25%, the result is pixelated. The output from Autostitch is pretty much what I get from any input except the JPG's extracted from the RAW EXIF's. Anyway, with JPG in, JPG out, there's bound to be a lot of quality loss. Apparently, it can't handle that many JPG's any better.
Since Autostitch can't handle TIFF's, I converted them to JPG's the same resolution. The PTGui version was created with TIFF images, 4256 x 2848 Px, and has some blending problems which could be handled in PS, but I haven't tried. Thanks to OpenCL GPU acceleration PTGui is able to stitch a 1 gigapixel panorama in about 25 seconds on usual computers. Keeping in mind that this is a 360° pano, there's almost sure to be a problem with Autostitch. PTGui is a graphical user interface for panorama tools (hence the name) or stitching application it transform individual pictures into a panoramic image. Thanks to OpenCL GPU acceleration PTGui is able to stitch a 1 gigapixel panorama in about 25 seconds on usual computers. I used the same images for both of the following panoramas. PTGui costs more than Panorama Maker 4, but it works, and you have complete control of the entire process - something you don't have with either of the others.

The results are unpredictable and usually awful, and you have to use Photoshop free transform to fix them.Īfter my unfortunate experiences with the demo version of Autostitch, I decided not to buy Autopano Pro. When working with vertical panos, Autostitch and Arcsoft both try to compensate for parallax by stretching or "squeezing" the top images. The Arcsoft "autoselect" doesn't work very well, often selecting more images than are in the pano, then you have to deselelect the incorrectly selected shots. If you rotate the images, Arcsoft will overwrite your originals, and will sometimes write unreadable files (this happened to me with two TIFF images in a 10 image pano). If you work from your original photos, beware of Arcsoft. I have several panos that neither the demo version of Autostitch nor the "Pro" version of Arcsoft Panorama Maker 4.0 can handle.
