This isn’t actually a new feature, but apparently it isn’t one that was heavily touted in the past few iterations of the iPhone. Applying Vulcan logic to the situation, one might point out that raising the volume on the phone triggers the shutter on the camera, so it would only be logical that pressing the same on the headset piece would too. Simply bring up the camera app, set your camera as you want and press the volume + button to take the photo.
What does this mean for you photo-bugs? Well, better pictures! Set your phone on a steady surface and then using the remote shutter feature means nothing to shake and ultimately ruin the shot. It also means taking pictures of yourself or a portrait with your favorite celebrity doesn’t have to be 6 inches away and blurry because you were to busy holding still!
Apparently, there’s no need for an app for that.
