In another patent application that was filed by Apple on Thursday, it appears that the Cupertino-based company, if not actually gearing up to incorporate into the device, is researching interchangeable camera lenses for its flagship handset, the iPhone.
In case you haven't noticed, there's been an explosion of camera apps on the App Store lately and, for the most part, we've totally avoided them. However, when I saw Tripod Camera [App Store, $1.99] I had to stop and check it out. The idea is simple; use the iPhone's accelerometer to determine whether the picture you're taking is straight and compensate if it's not. It works incredibly well and even includes an anti-shake feature which only takes a picture when you're still.
If you're into taking nice photos with your iPhone, Tripod Camera is totally worth checking out. Video of it in action follows below!
