summary

is a term in art for a contrast between light and dark. The term is usually applied to bold contrasts affecting a whole composition, but is also more technically used by artists and art historians for the use of effects representing contrasts of light, not necessarily strong, to achieve a sense of volume in modeling three-dimensional objects such as the human body.

Further specialised uses of the term are "chiaroscuro woodcut", used for coloured woodcuts printed with different blocks, each using a different coloured ink, and "chiaroscuro drawing" used for drawings on coloured paper with drawing in a dark medium and white highlighting. The term is now also used in describing similar effects in the lighting of cinema and photography.
