Prosopagnosia, also called "face blindness," is a condition that makes it difficult for people to recognize
faces, even those of family members and close friends. Artist Chuck Close, who at first thought of his
condition as a reason to avoid creating portraits, came to believe that producing faces actually
strengthened his ability to recognize individuals. In fact, Close's body of work is largely portraits, which
might seem unexpected. His mediums range from ink and watercolor paintings to woodcuts to handmade
paper collages.
