★ iOS 5 Camera App, Cable Release

What a brilliant discovery by Macworld.

If you’re a photographer, then you know that a cable release is a tool to take a picture without touching your camera. Now, the iPhone can do this, too.
iOS 5 introduced many new features for photographers. Among these is the ability to use the Volume up button to take photos. As a result, the Volume up button on your headphones also works to take photos!
