I love photography with my iPhone. Since I got my iPhone 5 I have taken well over 11,000 pictures. One thing I wish I could do is take a photo with a remote shutter release. Sometimes – especially in low light – just depressing the virtual button on the screen (or the volume control) to snap a photo is enough to blur the image.
Today, I discovered that pressing the volume button on the iPhone's earphone cable will take a photo. Very handy – especially when you're trying to take a selfie at arm's length.
Of course this works equally well on other iOS devices as well as with third-party earphone volume controls.
