That's what happens when you take pictures. The right face is much bigger than the left face. Obviously, what causes this and how to correct it?

This should be caused by the focal length of the photographic lens.

The visual angle of the human eye is 50゜. In order to get a wider visual angle, general photographic equipment, such as mobile phones and cameras, are designed with shorter focal lengths, which are different from what the human eye sees. The shorter the focal length, the larger the viewing angle, the closer the lens, and the larger the object.

Your photo is enlarged because the camera lens is wide-angle, and your right face is closer to the camera than your left face.

Correction method:

1, frontal photography, so that both sides of the face are at the same distance from the lens. (However, a big nose is possible. )

2, long-distance photography, using the mobile phone screen to adjust the size, the role is equivalent to a standard camera to lengthen the focal length, which can achieve the effect of human perspective. (This is the best way)
