Cindy Sherman is a contemporary master of socially critical photography. She is a key figure of the “Pictures Generation,” a loose circle of American artists who came to artistic maturity and critical recognition during the early 1980s, a period notable for the rapid and widespread proliferation of mass media imagery. At first painting in a super-realist style in art school during the aftermath of American Feminism, Sherman turned to photography toward the end of the 1970s in order to explore a wide range of common female social roles, or personas.
