Painting was an essential aspect of Alberto Giacometti’s work besides sculpture. The artist created many painted portraits throughout his career, which allowed a close psychological analysis of his sitters. Giacometti frequently used the same models, especially his wife, Annette, and his younger brother, Diego, repeating the same portrait studies over and over again, as if eliminating layer by layer the outer appearance of a person in order to capture the inner essence. In his later paintings, such as Annette in the Studio, Giacometti often used internal frames reminiscent of mirrors, adding even more distance between the viewer and sitter and conjuring an impression of loneliness and isolation.
