What color reflector is usually used for indoor shooting?

If it is a super professional studio, it will use Mipolo board, that is, benzene board or foam board in thermal insulation materials. Generally, kt board can also be used instead, which is generally white, or tin foil can be turned into silver. Generally, there are only two kinds. The rest will be adjusted according to the problems found in the shooting and the shooting effect you want to achieve. If the lighting requirements are not high, you can also buy five ones directly.
