Apple released an ad for the iPhone 8 Plus, which shows off the phone’s big new feature, Portrait Lighting. The spot features a singer walking towards the camera, lit with the various lighting setups.

Portrait Lighting is a new feature for the iPhone, which uses software to apply several preset lighting effects to a subject’s face. The various presets — Natural Light, Studio Light, Contour Light, Stage Light, and Stage Light Mono — are still in beta, but it’s a neat effect that builds on the iPhone’s Portrait Mode.
