Which is better, taking a selfie or someone taking your picture?

Others shoot. Don't shoot the pure front and side, shoot the half side, that is, the face rotates to one side; Don't take close-up photos. Like ID photos, many people can easily take a big face by taking selfies with their mobile phones, and they can take half-length or seven-person photos (in my other answers, there are skills to explain portrait composition, just click on my avatar to view it); Don't use a wide-angle lens, it is more appropriate to use a medium focus or a telephoto, because a wide-angle lens will exaggerate the deformation and make your face fat; Don't use front lights and reversing lights. It's better to use front side lights. The front side light means that the angle between the light source and the model and the camera is about 50 degrees, which will form obvious contrast on the face and look slim. Don't look at it deliberately, many people will feel uncomfortable when shooting, or deliberately make expressions, which is a bit unlike themselves; The camera position is slightly higher. If you take a close-up, the camera position is slightly higher than the face, and if you take a bust, the camera position is more appropriate above the chest.
