Introduced alongside the iPhone 6s and iPhone 6s Plus in 2015, Live Photos are designed to add life and vitality to the standard still photo by adding a bit of motion. A Live Photo captures an extra 1.5 seconds of movement before and after a shot, animating an image with movement and sound.
Live Photos can be captured using the iPhone 6s, 6s Plus, SE, 7, and 7 Plus, and can be viewed on all devices running iOS 9, OS X El Capitan, and watchOS 2 or later.
Though Live Photos have been around since 2015, few social networks support them, and there have been limited ways for non-Apple users to view them. The addition of a LivePhotosKit API may help make Live Photos more popular.
