Especially for most girls who have no standard aesthetics, they are not very photogenic at first sight. Originally, we were just ordinary and not ugly, but once the camera angle was not chosen well, it would be ugly in minutes.
A big face will naturally choose to stay away from the phone. The space outside the face is larger than the face, which is a contrast. It seems that the face is not that big. In addition, light is also very important, which is why many online celebrities need lighting when taking pictures. Make proper use of natural things such as sunlight to make the looming face more attractive.
The scientific explanation of photo ugliness is the frozen face effect.
Psychologists at the University of California and Harvard University have found that people think people in videos look better than screenshots of the same video. In other words, even if you feel uncomfortable in the photo, don't worry, others will think you will look much better than the photo. This may be related to the way the impression of dynamic face is formed.
People will average the same face in different positions and different sides. This is consistent with the previous study that "the average face is more attractive". Another possibility is that "dynamic faces better activate our neural mechanism of facial recognition". After all, the camera was invented not long ago, and our brain's face recognition system was originally evolved to deal with dynamic faces, not static faces.
