iOS 7 is known for its parallax effect, but you can also add a dynamic wallpaper. The pickings are slim, but it’s still kind of a cool feature if you’re interested in something different. Dynamic wallpapers feature subtle animations, so that your background is moving.
To set a dynamic wallpaper, go to Settings>Wallpapers & Brightness>Choose Wallpaper>Dynamic (Under Apple Wallpaper).
Select the wallpaper you want and tap on “Set.” You can choose lockscreen, home screen or both. We usually just do both, but that’s up to you.
There are only two choices (We are using an iPhone 5 and don’t know if newer models come with more options). It’s a subtle effect, but it can be pretty cool.
