I thought I'd learn a little something about posing with your face, since I see how well people's photos (like @Angelipon 's!) turn out when they clearly know how to work their face!
I've never been one to be able to pose well---I use too much teeth, or I don't open my eyes enough, or I am awkwardly angled....but I never realize any of these things until I get the photos back, and then it's too late!
These tips seem great for learning a bit and then practicing at home until my next con...who's with me?!
