I’m eager to try this out: 

When framing a subject, you’ll have a number of different lighting options to choose from for giving your portrait different looks — things like Contour Light, Natural Light, Studio Light, Stage Light, and Stage Light Mono.

These “aren’t filters,” Apple says. Instead, the phone is actually studying your subject’s face and calculating the look based on light that’s actually in the scene using machine learning.

Check out PetaPixel or Apple’s site for larger sample images.
