What's the difference between a reflector and a light absorber?

In general photography, the camera will use a reflector and a light absorption plate.

Reflector-When taking photos or videos, weak light will bring negative effects such as snowflake, light color and blackening to the subject, so reflection is used to increase the brightness of the subject. Up to now, the most practical thing taken by film and television workers and photographers is that "rice pineapple" has also become a foam board. It has many small particles and is pure white. The light it reflects is the same as the environment, and the reflected light is scattered, so it is natural and the effect is excellent. There is also a mirror plate, which is usually used for photography. The light he turned out did not come loose, shining on the subject like a mirror! Whether it is a movie or a TV series, wedding photography or personal photo, it is inseparable.

Acoustic board-simple explanation and use is a tool to increase light, you know!
