Apple Live Photos is a camera feature introduced on the iPhone 6s that captures sound and movement a second and a half before and after a photo is taken to create a video-like effect.
Made up of audio and still photos, Live Photos are not video files, but more like animated GIFs. Every picture a user takes with an iPhone 6s running iOS 9 is a Live Photo. Live Photos are viewable across all Apple devices but do not work on any non-Apple devices, meaning that any iOS user can view a moving Live Photo no matter what OS version they have.
To make a Live Photo move, users simply tap on the picture. They can also set a Live Photo as the background on their iPhone’s home or lock screens. With iOS 9.1, Live Photos even detects when the user lower their camera and stops recording, so the feature doesn’t accidentally capture something the user doesn’t want to.
Instagram’s Boomerang is similar to Live Photos but only captures one second of video without audio. Boomerang photos work on any device.
