Robert Heinecken (1931–2006) was a pioneer of the postwar Los Angeles art scene who described himself as a "para-photographer" because his work stood beside or beyond traditional ideas of the medium. Published in conjunction with the first comprehensive museum exhibition of the artist's work since his death, this book covers four decades of his remarkable and unique practice, from the early 1960s through the late 1990s, with special emphasis on his early experiments with technique and materiality, which called into question the very definition of photography. As the most complete survey of Heinecken's oeuvre, this book sets his work in the context of twentieth-century photographic experimentation and conceptual art.
