What is up with all the angry faces?

The only pictures of Carly Fiorina that I ever see are really unflattering. I mean expression-wise. Without fail her facial expressions are almost comical in their extreme violence of emotion, which appears to be mainly anger.
Are there more calm moments of her that could be used? Is the press being unfair to her? Or is this really all she’s giving them to work with?
I admit that I have never listened to her speak.
