I've owned every version of the iPhone starting with the original, three of the four iterations of the iPad and, oh yeah, I write about Apple products almost every day. Despite all that, I still manage to stumble across features on devices such as the iPhone and iPad that I either never learned about or forgot existed. Case in point: I found out today that the volume controls on Apple headphones or EarPods can be used to remotely control the camera shutter. I know. I was amazed, too.
So here's how it works: Just like you can use the volume + button the side of the iPhone to snap a photo, the same thing applies to the volume buttons on official Apple headphones and EarPods. Simply bring up the camera app (or certain apps such as Camera+), set your camera as you want and press the volume + button to take the photo.
Setting your phone on a steady surface and then using the remote shutter feature means you'll never have to worry about a shaky hand ruining the shot. Also, the volume controls on Apple EarPods are a little over three feet (or almost exactly one meter) from the plug, which should work well for snapping a photo of yourself and a few friends without dealing with a third-party camera timer app.
I can't be the only one who missed this feature when it was originally implemented a couple of years back, right? Right?!
