Apple Watch: Use camera remote

You can use the Apple Watch as a remote viewfinder for your iPhone. With this option, you can set the camera up, walk into the frame and make sure the photo looks great, then take a photo. It's a cool way to be in the photo without resorting to a selfie stick and a timer. 

How To:

Open the Camera app on your iPhone, then open the “Camera Remote” on your Apple Watch. You can choose to have none or a 3-second timer. You can turn on Flash and Live camera in the settings section of the Watch app. When you're ready, hit the “Capture” button. After you’ve taken the picture, you are able to view the picture straight from the watch.
