The lens inside the centered camera is crooked

This situation occurs mainly because the magnification of the center of the lens is inconsistent with the magnification of the edge of the lens. The magnification of the center of the lens is smaller. When taking pictures, the face is generally in the middle, and the chin is at the edge of the lens. , the lens edge has a large magnification, so the chin is elongated and the face is magnified.

The longer the focal length, the greater the magnification difference between the center and the edge of the lens, and the more obvious this change will be. Therefore, it is recommended that you keep your phone as far away from the face as possible when taking selfies to avoid this situation.
