The Smile Shutter feature on the Nikon Coolpix S8100 is pretty cool. It's a self-time option that uses face detection and triggers the shutter when the subject smiles. This is Jenni's dad Dan, helping me test it out. I also used it for some passport-style self-portraits and it worked great. It seemed to be a little temperamental with my beard but with clean-shaven faces it appears to work perfectly.
