Live Streaming Fill Light is a dedicated lighting device used in live streaming scenarios to supplement the lighting. As the core fill light in the three-point lighting system, its main function is to soften the harsh shadows produced by the main light source. The overall brightness is lower than that of the main light. It is usually placed on the opposite side of the camera from the main light and adjusts the brightness to control the amount of remaining shadows in the picture, achieving a uniform and natural lighting effect for the picture.
