Light art or the art of light is generally referring to a visual art form in which (physical) light is the main, if not sole medium of creation. Uses of the term differ drastically in incongruence; definitions, if existing, vary in several aspects. Since light is the medium for visual perception, this way all visual art could be considered light art absurdly enough; but most pieces of art are valid and coherent without reflecting on this basic perceptual fact. Some approaches on these grounds also include into light art those forms of art where light is not any medium contributing to the artwork, but is depicted. Thus, luminism may also refer to light art in the above sense, its previous usage point to painterly styles: either as an other label for the Caravaggisti in the baroque, or 19th and 20th centuries, fundamentally impressionist schools.
