Explain the difference between cross-hatching and impasto in creating a sense of texture. Why would an artist select one over the other?

Answer:

Cross-hatching creates the appearance of texture with intersecting lines of different values, while impasto creates actual, raised texture by applying thick layers of paint. An artist might choose cross-hatching for a controlled drawn effect or to suggest texture in a two-dimensional way. An artist would choose impasto when wanting the surface to be physically uneven and for the paint to catch light and create a more tactile effect.
