Apple posted a video dubbed "Portraits of Her", which promotes the new and improved Portrait mode of the iPhone 8 Plus and iPhone X, specifically the cool Portrait Lighting feature. But the video shows the effect done on video - something the actual iPhones can't pull off. It does look quite cool though, maybe we'll see something similar in future iPhones. At any rate, it was cool to see what this feature could do in motion. Source
