If you want to position your iPhone for a photo and then take the photo from a distance, you can use your Apple Watch to view the iPhone camera image and take the photo. You can also use your Apple Watch to set a shutter timer—this gives you time to lower your wrist and raise your eyes when you’re in the shot.
To function as a camera remote, your Apple Watch needs to be within normal Bluetooth range of your iPhone (about 33 feet or 10 meters).
