Photoshop CS3
I built a Photomontage-style layer blending feature in Photoshop CS3. The most common usage is panoramic stitching; simply leave the "Blend images together" checkbox checked when using Photomerge. The feature can also be used by selecting "Auto-blend layers" from the Edit menu.
The blending algorithm uses my new, efficient approach to gradient-domain compositing that was published at SIGGRAPH 2007.
A final version CS3 was recently released, and the feature is getting rave reviews. I've collected a few links.

- Photoshop Elements 6
- Microsoft Groupshot, built by Alex Colburn and Michael Cohen, was based on our Photomontage research. People seem to like it, and the software was recently demo-ed at CES 2007.
Three new features based on my Photomontage research shipped in Photoshop Elements 6.
