Actually, the bug had nothing to do with overlap or our ability to align images - it was a simple coding error that could cause the first image we encountered to be rejected. The bug is fixed in today's update release.

I am surprised this was a bug, even if it is very encouraging to hear of corrected bugs solving problems! My hypothesis was that the difficulty to stitch had to do with the mismatch between front and back scene when you superpose pictures 3 and 4.

I myself shoot panoramas without the aid of a dedicated pano head, so I get similar mismatches between adjascent pictures, when the front scene is too close to the camera. And I actually got into trouble as a started stitching such panoramas with Autopano Pro, which is not a bad program; I got a lot of ghosts at the boundaries of some frames. I tried the same set of pictures with ICE and was very surprised to see that this worked! Congratulations.

Now... from a purely optical point of view, it should not work. Can you tell something about your matching strategy without giving your dearest secrets away? My interest in this is to understand what ICE does to my pictures...

It looks like you've hit a bug that we have fixed for our 1.1 release. Please look for an announcement on this forum for an update to ICE in the next few days. I downloaded your images and was able to stitch 4/4 with the fixed ICE.

Sure.
As a side note, I managed to convince it to work by asking it to stitch images 1 & 2, which it claimed it couldn't do, but then the preview button showed a stitched image, so I saved that, and then had it stitch that first one with images 3 & 4. The result wasn't ideal, but it worked.

pics 004.jpg is the one it has trouble with.

Would you be willing to share the images with us for diagnostic purposes?

fails to stitch all images

Hi - on my first try with 4 images - a basic horizontal rotation panorama - it will only stitch the 3 rightmost images together. I've tried with subsets, including only the 2 leftmost images, but it can't figure out how to stitch image 1 & 2 (of 1-4) together. Image 2 overlaps about 50% of image 1, so I can't figure out why it won't work. Exposure is reasonably similar, though image 2 is somewhat brighter than image 1. The set is of the inside of a stadium from adjacent to the press box, covering about 180 degrees field of view. Any suggestions? Is there any way to "help" the algorithm? Thank you!
