On the iPhone 6s and newer models, you can use the "real-time photo" function to record everything before and after taking photos for 1.5 seconds, which is the same as taking ordinary photos. Just turn on the real-time photo switch in the camera and press the shutter to shoot.
Live photos can take all the pictures within 1.5 seconds before and after the photos. You can open the live photo, find the most satisfactory picture and set it as the main photo.

The live photos on the iPhone camera are Chinese translations of the original live photos; Live photos can be accompanied by sound. The function is to record 1.5 seconds of dynamic video before taking pictures. When the user deeply presses the photo, the photo will automatically play the dynamic effect.
Apple's live photos capture not static moments but dynamic moments. If you take a portrait, the portrait will move or blink, and the picture looks a bit like a GIF animation or a short video.
On iOS9 devices that don't support 3D Touch, users need to press and hold to play real-time photos. After the official release of OS X El Capitan system on September 30th, Mac devices can view these photos in the photo application.
