Over five decades, Robert Heinecken's work as an artist and teacher radically expanded the reach of photography. A precursor to appropriation artists of the 1980s, Heinecken is known for series like the influential "Are You Rea" (1966-67), in which he used magazine pages placed on light tables to create unexpected juxtapositions of advertising and feature photography. Deemed a "para-photographer" for his unconventional processes and irreverent attitude, Heinecken typically worked from found images, transforming them through methods like lithography, etching, and direct-exposure photograms.
