About tenebrism

Tenebrism, from Italian ("dark, gloomy, mysterious"), also occasionally called dramatic illumination, is a style of painting using especially pronounced chiaroscuro, where there are violent contrasts of light and dark, and where darkness becomes a dominating feature of the image. The technique was developed to add drama to an image through a spotlight effect, and is common in Baroque paintings. Tenebrism is used only to obtain a dramatic impact while chiaroscuro is a broader term, also covering the use of less extreme contrasts of light to enhance the illusion of three-dimensionality.
