Black reflector and diffuser

Black reflector
This kind of reflector is unique because it is not technically a reflector. It is a "dimming plate" or "absorbent plate". The use of other reflectors is based on the light addition method, the purpose is to add light to the scene. The use of black reflectors is the use of dimming methods to reduce the amount of light. Why use a black reflector? For various reasons, people often have to use annoying top light to shoot. Human faces photographed with this kind of light often have "raccoon eyes." By putting the black reflector on the head of your subject, the overhead light can be reduced.

Soft light board
It plays a role of blocking and weakening the light between the sun or light and the subject or person, which can soften the light and reduce the contrast. It can be used when the light is strong and you don't want to change the shooting angle to lose the background, or when the light is softened to reduce the projection of the subject.

Use
The white reflector has natural and soft light, and is often used for general fill light. The silver reflector is as bright as a mirror and reflects strong light, and is often used to create eye catching light. The golden reflector provides warm light, and the light is stronger. The difference between it and the silver reflector is that the golden reflector is generally used as the main light for portrait photography, and the silver reflector is often used as the auxiliary light.

Reflective effect comparison
The reflector is a supplementary light device in shooting. The common gold and silver double-sided foldable reflector is often used to improve the light, make the flat picture fuller, and better highlight the subject. Generally speaking, the role of the reflector is limited to this, but in fact, the purpose of the reflector is far more than these. After modification, the reflector can also be used for peculiar purposes.
