Apple has shared two brief new tutorial videos on its YouTube channel, explaining the operation of the new Portrait Lighting feature on the iPhone 8 Plus. The function was introduced with the iPhone 8 generation and the iPhone X and lets the user add a variety of simulated lighting effects to portrait images.
The device uses its dual-camera and machine learning to produce a depth-map of the image and apply lighting and blur effects to the scene. Available effects include Natural Light, Studio Light, Contour Light, Stage Light and Stage Light Monochrome.
Portrait Lighting can be activated while shooting or applied in editing at a later stage. The first of the tutorials focuses on Portrait Lighting in shooting mode, the second shows how to apply the effect when editing through the Photos app.
