Final answer:
Chiaroscuro in artwork refers to the contrast between light and dark, an artistic technique that creates the illusion of volume and depth.
Step-by-step explanation:
Chiaroscuro in a work of art relates to C. light and dark. This artistic technique was popularized during the Renaissance and involves the use of exaggerated light contrasts to create the illusion of volume. Traditionally, shadows in art were represented as dark glazes with little color interest, but with chiaroscuro, artists began to model form through the use of light and shade, lending a three-dimensional presence to the objects and figures depicted in their work. Artists like Michelangelo used techniques such as hatching and cross-hatching to achieve these effects, while others like Georges de la Tour are known for their religious scenes that employed chiaroscuro to convey drama and emotion. The contrast between light and dark in chiaroscuro gives depth and intensity to the art, far beyond the earlier more muted and flat representations.
