Light value refers to the relative brightness or intensity of light within an image, composition, or design. It is a fundamental concept in the field of visual arts and photography, which involves the manipulation and understanding of light in order to achieve desired effects.
In art, light value is used to describe the range of tones from light to dark that are present in a work. This includes the highlights, midtones, shadows, and all the subtle gradations in between.

It plays a significant role in creating the mood, atmosphere, and emphasis within an image or artwork. By manipulating the light values, artists and photographers can evoke emotions, direct the viewer's attention, and create a particular aesthetic result.
Overall, light value is a key element in the visual interpretation and communication of an image, as it determines the appearance, impact, and overall visual appeal of the composition.
