Dramatic Focus Changes

You know those focus changes when the camera suddenly shifts to someone in the background to catch their reaction or other humorous activity? The iPhone camera app actually makes this very easy with its tap-based focus. Just tap anywhere on the screen, and the app will autofocus there immediately. Do this quickly and accurately for fun takes or more dramatic switches to a new subject. It’s a lot easier in landscape mode where you have more freedom of movement for your fingers!
