Lets break this down a bit more, first let’s learn what the term actually means. In Italian the word chiaro means light, and scuro means dark. -- Chiaroscuro. Today, the paintings of Caravaggio are probably the most synonymous for this effect. As artists we learn best via visual stimulus, so everyone go look at some of Caravaggio’s work on line and you will quickly get the idea. So for the artist, this term means more specifically, a strong directional light creating a bold contrast between the lights and the darks over the entire composition. Employing the effect would mean to light the subject from one predominate source, typically from the side. As the directional light falls across the form it will create a strong shadow edge. As this edge follows the form of the object a strong three dimensional look will be achieved. All secondary light sources ie reflected lights are kept subdued to the predominate light.
