How is light used in art?

Light in art serves both as a medium and a tool for creating mood, depth, and emphasis. Artists manipulate natural and artificial light to enhance textures, colors, and forms, guiding the viewer's eye and evoking emotions. Techniques such as chiaroscuro use contrasts of light and shadow to add drama, while light itself can be a subject, as seen in installations that explore illumination and perception. Overall, light plays a crucial role in shaping the visual experience and narrative of a work of art.
