Can white paper really fill the light?

If your camera can adjust its brightness, there will be more choices when shooting. Using different colors and materials of paper will also increase different effects when taking pictures. Opening holes in the paper will give you different light when taking pictures.

Photographic fill light refers to making enough light by artificial methods to get normal exposure photos, such as using a flash, but the photos you see at this time will feel very dull and have no sense of hierarchy; Secondly, in the case of sufficient light, local light compensation, such as the shadow of the face or other parts in portrait photography, needs to use reflector or other light sources for light compensation to get a layered and three-dimensional photo.
