Frank Noelker did a series of portraits of chimpanzees that were once used in entertainment, medical research, and the like, but now live in sanctuaries in North America. The portraits are hauntingly beautiful, and really respect the individual experiences of these beings, like Sue Ellen (above).
(I am reminded of the monkey and ape portraits by Jill Greenberg. While I like some of those images, overall her work has such a commercial slickness that it kinda freaks me out.)
