Chiaroscuro is one of the most important and fundamental techniques in art, particularly in any style that makes use of realism. The textbook definition for chiaroscuro (Italian for “light-dark“) is simply the use of value (shading) to create an illusion of depth and volume on a two-dimensional surface. More commonly, it refers to the use of strong contrast or unusual lighting to create a strong dramatic effect.

A painting or drawing, even if it is proportionally correct, looks flat and lifeless without shading. Chiaroscuro is an essential element, especially in portraits and still life, where it is not only functional – giving the shapes depth and definition – but a potentially explosive means of conveying drama and emotion.

The basis of chiaroscuro stems from the observation of the way light behaves on surfaces. By reproducing this behavior accurately on paper or canvas, you can create an image that is visually authentic to the eye of the viewer. We all have an intuitive grasp of how light interacts with the world around us – for instance, we all expect to see an area of brightness where light reflects off an object, or a patch of shadow where light is blocked. But light sometimes behaves in more subtle ways of which we aren’t always conscious. The artist can take advantage of these subtleties to create a convincing chiaroscuro effect.

Adding the dimension of color creates a whole new set of complexities in working with chiaroscuro. Because the level of intensity in the lighting changes the way we perceive a given hue, color chiaroscuro is more challenging for artists to work with than just black and white or gray-scale (more on light and color here). But black and white is the best way to learn chiaroscuro, since it illustrates how powerful a tool it is even in the absence of color. With a little study, it is a simple and effective application of the comparatively difficult science of optical physics.

Chiaroscuro first came to prominent use during the Italian Renaissance. An especially popular form known as tenebrism, pioneered by painters such as Caravaggio, used exaggerated lighting contrast for heightened effect. This was a favorite style of painters like Rembrandt and El Greco and heavily influenced later styles of painting in the 19th and 20th centuries.

It is interesting to note that many of the famed artists who made the strongest use of chiaroscuro were also great draftsmen, having first mastered the use of shading through drawings in mediums such as pencil or silverpoint.
