The camera filmed how a woman dressed up at a dresser

The optical path is reversible, as long as the machine is not facing the mirror, it cannot shoot the machine itself. The principle of reflection is that the angle of incidence and the angle of reflection are equal, and the fact that a woman can be seen in the lens only indicates that the woman can see the camera, and the angle between the machine and the mirror is the same. Of course, you can't see the camera.

The position of the woman should be far away from the right angle in front of the mirror, most of them should be oblique at 30-45 degrees, and the camera, placed on the other side, is also facing the mirror at an inclination of 30-45 degrees, which can make up for the panorama!
