OK, so you are like everyone else when taking photos with a camera in that you have a hard time keeping the camera still. Or, you want to use the iPhone and take a picture of yourself, but your arms are too short. Here is a helpful tip.
Set the camera down and plug in your ear buds. Yes, those earbuds have a button that when clicked will take a photo with the camera on your iPhone or iPad. If you are on video mode, clicking the button will turn on and off the record action.
Note: you do need the earbuds with the built in microphone.
