Is mirror or camera more accurate ?
1. Reflection (Mirror): A mirror shows you how you look from your own point of view (as a reflection), while a camera shows you how others perceive you (with no lateral inversion).
2. Camera: In terms of technical accuracy, a high-quality camera is often more accurate because it provides a more objective, external perspective. However, mirrors are more intuitive for daily use since they match your direct visual perception, even if they invert left and right.
Conclusion:
If you're talking about how you look to others then click your picture with a back camera then zoom it and it will show more "accurate" you. But clicking photos with a back camera also differ according to your facial features like if you have a oval or round face then your face will appear more big than it actually is and if your face is kind of long, diamond or thin kind of face then it will appear more attractive comparing to face with round or oval shape face. But i swear people look more attractive in real life than in photos(my experience) because the people who look kind of unattractive in photos were more attractive when i met them in person and the people who are attractive in photos are also attractive when i met them in person.
