Shading in art is important for many reasons. First, it adds realism to a drawing or painting. Next, it gives your work a sense of depth, or three-dimensionality. Most importantly, it affects the emotional tone and emphasis of a composition. Dramatic shading, such as the chiaroscuro used by early modern painters such as Tintoretto and El Greco can add intensity and drama to a composition, while the much more graduated shading of the beaux arts school or of water colors, can create a sense of tranquillity or a pastoral mood. Shading can also be used to emphasize certain parts of a composition and de-emphasize others.
