How to adjust the lights, ask for guidance!

A: In addition to normal light consumption, that is, main light, auxiliary light, effect light (or decorative light), low-key photography can be used to hide unnecessary parts.

Use a small-caliber photographic lamp, cover the lamp cap with a piece of black paper (or opaque paper), and dig a hole with a diameter of 1 cm in the middle, so that the light emitted from the small hole can only hit the shooting subject, that is, you are done. The aperture through which light is transmitted can also be increased or decreased according to the size of the object.

This method is helpful to you, please like to forward it!
