Photo stitching app Doubletake has been updated to version 2.0, and boasts some nice new features introduced since the last time I mentioned it here.

Most obvious is better performance. Everything the app does is now noticeably faster, which makes it all the more fun to use.

But there’s also some new edit functions; iPhoto-style head-up panels for adjusting images, and better still adjusting their geometric placement within the stitched final result. With the geometry controls, you can rescale, tilt and rotate images in situ; this is a huge help when it comes to fine-tuning the stitching of one image to another.

What’s a little confusing is that there’s plain old version 2.0, but also a newly-released version 2.0b17 - I’ve managed to get both of them side-by-side in my Applications folder without intending to. The beta has some separate release notes which detail even more new stuff; the Free Perspective mode looks particularly fun, and there’s also Exposure matching and QTVR export too. Lots of stuff to play with.

Doubletake 2.0 is a free upgrade to existing license holders; a fresh license is only $16. The new version requires OS X 10.4.
