Apple's Live Photos, introduced in 2015, are photos that capture 1.5 seconds of video before and after you take a picture, with the aim of adding a little bit of life and movement to still images.
When you take a photo with an iPhone, not every shot comes out crisp and clear, but with Live Photos, if you get a blurry image, you can open it up and see if other frames you captured are clearer. If so, you can choose a new "key photo," aka the main photo that you see in your camera roll. Here's how:
- Open up the Photos app.
- Choose a Live Photo.
- Tap on "Edit" in the upper right hand corner of the display.
- Using the photo navigation bar at the bottom of the image, tap the thumbnails to browse through the frames captured for the Live Photo.
- If you find a better still, tap on "Make Key Photo" to select it.
- If you like your original still image best, tap "Cancel" to exit out of the editing interface.
Selecting a key photo from a Live Photo is a feature that was introduced in iOS 11, so to edit your photos and choose a new main photo, you'll need an iOS device that's running iOS 11. You can also make these edits on a Mac running macOS High Sierra.
It's worth noting that choosing a new key photo from a Live Photo does change the resolution a bit and lowers the overall quality of the photo. On a standard iPhone X, for example, a regular shot is 4032 x 3024, but when changing the key photo, that drops to 3662 x 2744.
