Chiaroscuro in art is the use of strong contrasts between light and dark.
This is usually done to make the composition a lot more dramatic. It is also a technical term used by art historians and artists for the contrast of light. It gives a sense of volume when modelling three-dimensional (or 3D) figures. Similar effects used in photography and cinematography are also called chiaroscuro.
