Which is closer to others' eyes, looking in the mirror or taking pictures?

Strictly speaking, looking in the mirror and taking photos are not what others think of themselves. Relatively speaking, looking in the mirror is closer to what others think of themselves.

There is an error between the self presented by mirror through optical reflection and the self presented by mobile phone through traditional photography principle and the real self. Only relatively speaking, the mirror is more real than the self presented by photography, and more in line with the self in the eyes of others. Because the so-called photo, because the shooting light and angle include self-processing function, the photo deviates greatly from the actual situation;

Compared with mirror image, the related factors that lead to errors are reduced. Because the error of looking in the mirror is smaller than that of looking in the photo, looking in the mirror is closer to other people's eyes.

Principle of plane mirror

A plane mirror can form an isometric image, which is mirror symmetry. As long as it is a plane mirror, the image formed in an isotropic homogeneous medium will not be deformed. If you look at a flat mirror, you will find that your face is getting fat, that is, the problem of your face is not the problem of the mirror.

The photos taken by the camera can deceive people. The "deception" here includes not only image processing such as PS or beauty, but also the degree of deformation of photos taken under different equivalent focal lengths. Some exaggerated shapes may be shot with a short-focus fisheye lens or a super wide-angle lens.
