an artist who specializes in chiaroscuro, the technique of using strong contrasts between light and dark in their work.
From chiaroscuro (Italian chiaro 'clear' + scuro 'dark') plus -ist (one who practices). The suffix -ist makes it refer to a person who specializes in this technique.
Famous chiaroscurists like Rembrandt and Caravaggio understood that human eyes are drawn to light, so by controlling where the light hits in a painting, they controlled exactly where your attention goes!
