Getting someone to relax in front of a camera is a lot easier when they can see how they look. Apple acknowledges this on its new foldable iPhone Duo with a feature called Duo Preview, which shows a live preview on the outer display.
This way, whoever you're photographing can adjust their pose, fix their hair, or straighten their costume before you take the shot. It works for both photos and videos.
With Duo Preview enabled, the outer display mirrors what's captured by the main camera, so it feels like looking in a mirror rather than at a viewfinder. The outer display also shows only the preview, so there are no camera controls on that side obstructing the view. Keep reading to learn how to use it.
How to Use Duo Preview
- Unfold your iPhone Duo so you're looking at the inner display.
- Open the Camera app.
- Tap the Outer Display Options button (it looks like a column view icon) in the top-left corner, then tap Duo Preview.
- Point the rear cameras at your subject, and they'll see a mirrored live preview of the frame on the outer display so they can adjust before you shoot.
- Tap the shutter button to take a photo or Record to shoot video. You can also press either volume button or click the Camera Control.
Duo Preview is one of several Camera features that take advantage of the Duo's foldable design, alongside Kid Cue and Smart Take. Check out our full guide to see what the iPhone Duo's camera can and can't do for the rest.
