The guys over on LiveSide just spotted an update to ICE, the “Image Composite Editor” created by Microsoft Research. If you’ve never heard of this tool before, it’s pretty impressive. Basically, it’s the technology that’s used “under the hood” in Windows Live Photo Gallery to stitch photos together in order to create panoramic images. But it does more than that, too. ICE also lets you change the orientation of a photo to give the impression a tilt/shift lens was used, set the midpoint of a 360-degree panorama, or use a prospective projection with your images instead of a cylindrical one. (For what this all means, check out the Windows Live Photo & Video blog post about ICE).
You can also export your ICE images to Deep Zoom and HD View and there’s an ICE add-in for use in Photo Gallery.
Now, with the new update to ICE, it supports a “Publish to Photosynth” option. This lets you send your full-resolution panoramas to the Microsoft Photosynth website, which has also been updated to accommodate the new, wider imagery. Look for the new “Expand/Contract Viewer” button to the right of the plus sign in the Photosynth controls.
