Is a photo or your mirror image a more accurate representation of how other people see you?

Neither of them. The way human eye sees the world is completely different from the image you see on the photo and mirror. First of all, the plane mirror reverses the image. It reverses letters and words the same way it does with your face. Also remember that the mirror is an image of something else, so it carries some distortion. It also unshapes your face. On the other hand, the photo shows third-dimension objects on a two-dimension surface. So, the image on the photo is unreal if compared to human eye and it is also distorted from reality. As you will never see yourself, try to understand how people happen to see you.
