Heinecken completed his bachelor's and master's degrees in art at UCLA, where he studied printmaking as well as photography
In the late 1960s, he also began cutting up popular magazines such as Time and Vogue and inserting sexual or pornographic images into them. He would place his collage-publications back on newsstands in Los Angeles to be sold to unsuspecting buyers.
In the 1980s, he created several series on American news television that involved photographing images on the television or exposing the light of a television set directly to paper to create what he called "videograms
During his life he was mainly shown in traditional photography galleries, but two contemporary art galleries in L.A. began staging exhibitions of his work after his death: Marc Selwyn Fine Art and Cherry and Martin. Curators like Eva Respini at the Museum of Modern Art now place his work in a conceptual art lineage, associating him with Pictures Generations artists such as Cindy Sherman, John Baldessari and Richard Prince.Wikipedia
