What devices did Renaissance artists use to make their paintings more lifelike?

In an attempt to revert back to classical painting, Renaissance artists used several techniques in their art to accomplish lifelike paintings. These included Humanism/Perspective which applied a three-dimensional appearance on a two-dimensional object. Sfumato, a toning down process demonstrated in 'Mona Lisa'. Chiaroscuro which used strong contrasts of light and dark. Fresco which was a form of mural painting on new lime plaster. Foreshadowing which created an illusion of objects receding in the background.
