Remember those earbuds that came with your iPhone that you probably still have in the packaging? Yeah those. Here’s helpful tip: according to Macworld you can use those to take pictures simply by pressing the volume button on the earbuds. It doesn’t stop there though — this trick can even be used with a Bluetooth device that has volume buttons on it as well. So, if you’re wanting to boost your photography this is a great, simple way. Enjoy!
