How to use your Android Wear smartwatch as a remote shutter for a smartphone camera
How would this feature be of any use? Well, imagine that you wanted to take a picture with you in it – you could place your phone on a flat surface, aim it, then go into the frame with your buddies and press the shutter from your smartwatch. Or you can use it to spy on people, although that wouldn't be a nice thing to do, and don't blame us if you get in trouble for being too nosy.
Anyway, let's get to business.
The moment you open Google Camera on your phone, your smartwatch will display a new card labeled "Remote". If you tap it, your watch's display will turn into a big shutter key. Tapping the key enables a 3-second timer and then a photo is taken. After the photo has been captured, a preview of it is shown on the watch's display.
There are several limitations to this method, however. Firstly, Google Camera can't turn your watch into a viewfinder – you can't see what your image looks like until it has been shot. Also, the aforementioned delay can't be disabled, and adjusting camera settings is out of the question.
The alternatives: Wear Camera Remote
Alternatively, there's a neat little app called Wear Camera Remote. Unlike Google Camera, it can display an image preview on your Android Wear watch, and if that's not enough, you get control over the flash setting and the camera's self-timer feature. Better yet, the application is free to download and use.
To use Wear Camera Remote, launch the app from your smartwatch. You do this either with a voice command or manually, by tapping on the screen, scrolling all the way down to the "Start..." option, and launching the app from there. Note that the app will start and will be capable of taking pictures even when your phone's display is off.
If neither of these work, or if you need to have more control over the image being taken, there are two more apps you may try. They'll cost you a buck or two, however.
