Why do some people look ugly but beautiful when they take pictures?

Because when you actually observe people with the naked eye, what you see is a 3d stereoscopic image, and photography is to turn this image into a 2d plane image. At this time, some people's five senses will be deformed, which will lead to the difference from the actual observation, which is called "photogenic" and "photogenic". So the photos taken by people with three-dimensional facial features are good. People with long facial features, even if they are beautiful, will take ordinary photos.
