One of Photosynth's new features allows users to create their own walking tour, like this one of Edinburgh Castle. (Check out the embed below for the full interactive experience.)

Microsoft has announced a few new features for its Photosynth software. Formally a panorama-focused tool, Photosynth has expanded to include a spin, walk and wall capture mode. You can still create panoramas with Photosynth, but the viewing platform has changed to give the 360-degree photos a more immersive, active feel. The new Photosynth features are still in preview and not yet officially integrated into the main Photosynth site, but you can check them out here.

Microsoft explained the new features and gave examples in a press release:

This technical preview highlights the third generation of our 3D technology. It’s a dramatic step forward in smoothness and simplicity, and is what we now recommend for anyone with a D-SLR or a point-and-shoot camera. Once a synth is created you can easily share on Facebook, Twitter or via embed with a few simple clicks.

Spin: Spin around an object as small as a cup and saucer or as large as glacial peak.
