Cupid and Centaur by Joel Peter Witkin, 1992
His work is amazing... decidedly macabre, dark, and haunting but maintains a sense of poetic beauty and romance. His photographs often include skeletons, corpses, dismembered bodies, dwarfs, transsexuals, hermaphrodites, and deformed humans. Witkin's technique draws on early daguerreotype processes, scratching the negatives, and bleaching/toning the prints.
