I ran some more photos though PTGui. Managed to crash it twice, and it couldn't auto-generate control points on a few photos. It also can't merge portrait and landscape photos, which seems like a weird limitation.

These are just roughs for evaluating the stitching software. When I actually make panoramas for reals, these will have the vignetting corrected, and the noise (hopefully) removed, and the exposure adjusted, and all those things that I secretly do to my photos in post-processing. They'll also all line up correctly too, which not all of these do. (On some of them I had to enter control points by hand, and being just a tiny bit off will rotate the whole frame.) (And they certainly won't have stupid watermarks all over them.)

So, here's your homework assignment:

I've uploaded the original resolution (3872x2592 etc.) JPGs from some of the above tests. Download these and stitch them back together with your favorite software, and then tell me how it goes. Some of them were taken hand-held, and so the camera moves position from one frame to the next. I was thinking of uploading the NEFs, but oh well.

Here are the files:

Have fun.

P.S. If you're wondering about the Burning Man ones; I climbed up a 40ft. tower, and stayed there until I was no longer afraid of hights. I was psyching myself up for an experience I had later that night — the night of the burn. I happened to have my camera with me at the time, and captured these (and other) photos of the sunset. They were all done hand-held, while hanging off a wobblely tower, keep that in mind when you can see the stars in the sky in some of them.

Hey, have you tried any square panoramas, tiling images in both directions? Also, how hard/effective is automatic keystone correction? Do any of the tools you've used support using one or more wide angle overview images to help with feature identification?

I'm looking at doing a bit of what amounts to scanning large, flat images, but without a tripod, and wondering how hard it's likely to be.
