With Google Cardboard, you can take amazing trips to faraway places and feel like you’re actually there. But what if you could also use Cardboard to go back in time—to step inside personal moments like your favorite vacation or a holiday dinner with family? Now you can with the new Cardboard Camera app for Android.
Cardboard Camera turns the smartphone in your pocket into a virtual reality (VR) camera. It’s simple to take a photo: just hold out your phone and move it around you in a circle. Later, when you place your phone inside a Google Cardboard viewer, you’ll get to experience something new: a VR photo.
