Photosynth and Microsoft Research Image Composite Editor team bring you the power to create and share beautifully stitched, seamless panoramas of almost any size. This release used two technologies together: ICE’s state-of-the-art automatic image stitcher that makes it easy to create beautifully toned panoramas of more than a billion pixels, and Photosynth’s Seadragon-based display tech that gives you a buttery-smooth way to explore every corner of these enormous images. This release takes one significant step in by integrating panoramas. With this release you can choose different tools to make 3D or seamless panoramas. Here's an example. Make sure you hit "expand" button in viewer to see it in all it's glory:
Rail-to-rail viewing; completely redesigned viewing page still contains everything it used to, but the information that used to be squeezed alongside viewing area is now below it.
Zoomed-in highlights let you make a highlight of any part of any image. Check out the two highlights on this synth for example. They each show a full resolution portion of an image.
