Chiaroscuro is a painting technique, developed during the Renaissance, which uses strong tonal contrasts between the three-dimensional forms of light and dark for the model, often for dramatic effects.

Artists known for developing the technique include Leonardo da Vinci, Caravaggio and Rembrandt. It is a fundamental element of black and white and low photography.
