iOS provides a Portrait mode in the stock Camera app to owners of the dual-camera iPhone 7 Plus.
As you know, Portrait mode lets you take dramatic DSLR-like depth of field photographs where the camera automatically creates a beautifully blurred background while keeping the subject in the front sharp and in full focus.
Your iPhone 7 plus defaults to saving both the original twelve-megapixel photo and its depth of field counterpart, effectively doubling storage requirements for Portrait shots.
In this quick tutorial we're going to show you how you can easily disable photo duplicates for depth of field photos with just a few taps.
