Jill Greenberg's "Monkey Portraits" is being exhibited at the National Academies’ Keck Center in Washington, DC.

Here's a description:

Chimpanzees are our biological relatives. Never have the similarities between simians and humans been as amusingly and brilliantly captured as in “Monkey Portraits.” Jill Greenberg has spent 15 years photographing celebrities--from Clint Eastwood to Drew Barrymore--for leading publications, but has recently focused on actors of a different sort. She has been photographing monkeys and apes, many of whom have appeared on film or in television shows. Her intimate portraits of these animals convey a startling range of emotions and personalities, and evoke an almost eerie sense of recognition. These anthropomorphic photographs will cause you to wonder just how different we truly are.

The gallery is online, as well. (Be sure to check out all three pages of the gallery.) Her "End Times" gallery is also available online.
