Apple gives away a free app in iTunes each week, and the current app is definitely one you’ll want to get. 360 Panorama is an iPad and iPhone app which helps users to stitch together photographs to make a seamless panoramic shot.
This app will help budding photographers put together higher quality shots which can then be shared via Facebook, email, and more. While that might not sound impressive, I recall from my computer vision class in college that this trick takes a fair amount of skill to implement properly. (And it’s also really cool.)
The app is normally a buck but for now you can find it for free in iTunes.
