Paul Kooiker, a photographer based in Amsterdam, has created some incredible nude and erotic portraits. They run the gamut in tone from creepy and voyeuristic to ethereal. In 1996, his award-winning series called Untitled: Peeing Women in the Forest, was a series of shots, blurry and from a distance, of women peeing in the woods. Kooiker has published 13 photography books, all of which you can find on his website.
