The main reason why you look different in photos compared to real life is because of the camera angle, lighting, and other factors. In real life, you can move and adjust your facial expressions, poses, and angles to present yourself in the best light. In photos, however, the camera captures you in whatever angle and lighting it is set to, and doesn't necessarily capture your best angles. Additionally, photos can be edited to make you look different from how you appear in real life. To get the best results in photos, try to find the angle that works best for you, use natural lighting, and avoid too much editing.
