One of the Renaissance techniques used in this painting to make it look more realistic and three-dimensional is chiaroscuro. Chiaroscuro is the use of strong contrasts between light and dark areas to create the illusion of volume and depth in a two-dimensional artwork. In this painting, the artist has used chiaroscuro to create shadows and highlights on the figures and objects, giving them a sense of three-dimensionality and making them appear more lifelike.
