Hands-Free Camera You’ve happened upon a fabulous photo op, but there’s no one around to take your picture. Instead of settling for the Extended-Arm Selfie, use this free app to take a hands-free shot. How? Simply place your iPhone a few feet away, step into the camera’s frame, raise your hand, then close your palm. The app will pick up the gesture, activating a three-second countdown, followed by a snap.
