Standalone cameras and apps that can take 360-degree photos and videos are a must if they're essential to your job or if they fit your lifestyle. But if you find yourself taking spherical images merely once in a blue moon, you may not need them at all. Facebook's iOS and Android apps can now capture 360-degree photos without the help of a third-party application or an extra device. All you have to do is launch the app and pick the "360 Photo" option at the top of your News Feed. Press the blue button and follow the path on screen to complete a full spherical image -- you can then choose the photo's starting point.
