Halsman dabbled in experimental photography outside of his famous portrait of Dalí, creating deconstructed nudes, photographic mashups like this one of Marilyn Monroe and Chairman Mao, and more standard surrealist images — a naked woman in a demonic mask riding a wooden pig, for instance....
With his photography, Halsman’s stated goal was to explore the human face the way “Tolstoy and Dostoyevsky…had explored human nature, with psychological depth and honesty.”
Notice that the goal is not to find the “truth” of a subject, but to achieve “psychological depth and honesty.”
