The iPhone app, Camera Genius solves a few of the problems with the iPhone's built-in camera such asoor performance in low light, difficulty snapping the shutter when taking self-portraits, and its lack of a timer. The app also offers a sound-sensitive shutter release, so when you or friends shout "Cheese" or whatever, the camera will snap the photo.
