Most people know that the self-timer function on the iPhone is useful for taking a group photo or selfie – simply prop your iPhone up somewhere stable, tap the self-timer button, then run in front of the camera with your friends to be a part of the photo. However, you can also use the self-timer as a kind of remote trigger for an iPhone photo. This is really useful for when you’ve forgotten your earphones, and can’t trigger the shutter of your phone without having to resort to tapping the on screen shutter button. So next time you need to get a perfectly steady shot, set your iPhone up somewhere sturdy, compose the shot, then hit self-timer and stand back so as not to disturb the phone with your movements. Pro Tip: The iPhone has the additional benefit of having zero moving parts, in contrast to a DSLR for example. This means that when the photo is taken, there is absolutely zero movement within the iPhone itself, which in theory means the sharpest possible image capture. Pretty neat!
