Macworld reminds us of a cool trick for iPhone photographers that will enable steadier shots than using the volume button on their iPhone. The trick is related to the volume trigger button on your iPhone’s Remote Earbuds, where you open the camera app, and then use the volume button on the headphones as a trigger. This is already helpful for steadier shots, or taking a better front-facing shot.
However, this trick can even be used with a Bluetooth device, as a sort of wireless remote, once paired. Interested in more iOS 5 camera tricks? Check out the iPhone’s built-in panorama mode.
