Create Epic Live Photos
The iPhone 8 takes Live Photos and now you can edit Live Photos for a better looking photo and to create cool effects with your Live Photos so they bounce, loop or go in reverse without any third party apps.
Take a Live Photo with the main Photo option. If there is a small yellow circle in the options area you are taking a Live Photo. The phone will also say "LIVE" on the screen when you take a photo.
After you take the photo, tap on edit and then you can see options to change the key photo, turn sound off or automatically make the photo look better.
A new option appears if you swipe up on a Live Photo in the Photos app. Tap on the effect you want and your live photo will loop, bounce, or reverse. It's a really cool effect, but you should spend some time practicing with it since you need a steady photo with dominant motion for it to work well.
