Chiaroscuro

Also called light-dark modelling

This entry has not been translated yet and is shown in English.

The modelling of volume through strong, unbroken transitions from light to dark, with a small lit passage carrying the subject out of an enveloping ground. It is a compositional device as much as a lighting one: the shadow is not empty background but a mass with weight and edge.

Plan view: one small hard key well off to camera-left on the subject's lit side, raking across it at nearly sixty degrees off the camera axis, and nothing else — no fill, no reflector, the surrounding walls marked black so nothing returns, leaving the subject's far side to fall into an unbroken dark mass.

In practice

In criticism it names the whole light-dark drama. On set it usually means one hard key and the discipline to let everything else go.

Not to be confused with

Low keyA tonal strategy in which most of the frame sits in the lower register and a small, controlled area carries the light. The ratio is high, fill is minimal or absent, and form is described by the few edges that catch the key rather than by overall illumination.

Origin

Italian chiaro (light, clear) and oscuro (dark, obscure). In use for drawing on toned paper by the sixteenth century, well before it described painting or film.
