Additional, AE (autoexposure) lock allows you to meter the exposure on a single point of reference in the frame, and therefore will not change if you recompose from there.For when you're trying to focus on something but the iPhone keeps changing focus to something else (this doesn't happen a lot but sometimes the iPhone picks the wrong thing to focus on).
