Barbara Nitke began her photography career on Manhattan porn sets in 1982; the behind-the-scenes porn shoot work and more recent romantic BDSM-themed photos she's produced since are some of the most beautiful and compelling we've seen. (Don't miss the story of her 2001 lawsuit against John Ashcroft as well.)
