Shunt shooting: the light is in the same direction as the lens. The photos taken are relatively flat. The foreground is almost as bright as the background. The subject is right in front of the shadow, and the subject often blocks its shadow. It's called pursuing the light.

Backlight shooting: the light is directed at the lens. The photos taken are dark before and bright after, with only outlines. The subject is directly behind the shadow, and the subject is usually in its shadow. Is to shoot at the light display

Side light shooting: the light forms an angle with the lens direction (not perpendicular or equal), the foreground is bright and dark (the light and dark changes obviously), and the background behind it is completely bright. Usually, the shadow is in the front left, front right, rear left and rear right of the subject, and the shadow will not be blocked.

The front light means that the light is behind you, and the back light means that the light is in front of you.
