If you wonder what is more accurate mirror or camera, familiarity is also a key factor when it comes to how the image feels. You look at your face often, and your face is always upside down, so that a picture of you that isn't upside down can look odd even if it's a correct picture of your face. Visuals Clipping notes that this can be enhanced by expressions and by the exact moment of capture, as the differences between several photos captured under the same conditions are more apparent than in a single photo.
