fill light

Secondary illumination source

Fill light is supplementary illumination used in photography, film, and video to soften or eliminate shadows created by the main light source.

It's typically positioned opposite the key light and set at lower intensity, reducing contrast without overpowering the primary lighting scheme.

The cinematographer added fill light to reveal more detail in the actor's shadowed face.

In three-point lighting setups, fill light works alongside key light and backlight to create balanced, professional-looking images.
