"fill light" 的定义和意义

What is "fill light"?

Fill light is a lighting technique used in photography and film to reduce shadows and balance the overall exposure of a scene. It is typically used in conjunction with a key light, which provides the main illumination and creates primary shadows. The fill light is placed at a lower intensity and often positioned opposite the key light to soften the shadows and bring out details in the darker areas of the subject. This technique helps to create a more evenly lit image and reduce the contrast between light and shadow.
