If you start up the Ovi Store on your Nokia N900, you’ll see a new app called “QuickPanorama“ by Morpho showing as one of the newer entries.

QuickPanorama allows you to take panoramic pics by only moving the camera to capture a wide landscape. As Mark from TheNokiaBlog demonstrated :
This is a major timesaver as you dont need to take multiple pictures of one subject and stitch them together later.
The version of QuickPanorama on the Ovi Store right now, is a demo version that’s limited to a capture size of VGA (640 x 480). No doubt a Paid version would be able to capture a larger size if/when it becomes available.
