After going through public beta, iOS 10.1 is now in its final version. Aside from bug fixes, this update brings the Portrait mode feature to the iPhone 7 Plus’ camera. It offers a bokeh-like effect that makes it look like the photo is shot with a DSLR. The feature is said to currently be in beta. It’s best used on people and animals, according to CNET. The app will save a version of your photo with and without the feature enabled. You can’t edit photos after the fact. To achieve the Portrait mode effect, it has to be enabled when you take the shot.
If you want to get the feature, you can head to Settings > General > Software Update or update via iTubes. Check that you have a couple of gigabytes free and back up your iPhone on your computer or iCloud first. Keep the phone plugged in while updating.
