Chiaroscuro: Painting with a Spotlight
Imagine a face glowing in the dark, lit from one side as if by a single candle. Painters have created that effect for hundreds of years, and the technique has an Italian name, chiaroscuro. The word joins two older words that mean light and dark.
In a painting, chiaroscuro means using strong differences between bright areas and deep shadows. A flat shape on a canvas does not look solid. When one side of a cheek or an arm is bright and the other side fades into shadow, it begins to look round, as if you could reach out and touch it. Artists call this modeling.
Two painters famous for the style are Caravaggio, who worked in Italy around the year 1600, and Rembrandt, who worked in the Netherlands a little later. Their scenes often have a nearly black background. A beam of light falls on only the most important part of the picture, such as a face or a pair of hands. Your eyes go right to that spot.
Light can also tell a story. A bright spot may suggest hope, or a dark corner may hint that something is hidden. You can try the same idea at home. Set a lamp beside a pear on a table in a dim room, and notice how the shadow side turns deep and the bright side stands out.
