Chiaroscuro in art is characterized by strong contrasts between light and dark, usually bold contrasts affecting a whole composition. It is also a technical term used by artists and art historians for using contrasts of light to achieve a sense of volume in modeling three-dimensional objects such as the human body.(wiki)
What an amazing painter!
