Portraits—A Study of Features and Emotions
Research book on facial features: which features communicate emotions best?
At first, I was trying to determine if the slightest form of expression could be discerned by a viewer,
but the models...any model couldn't tell the difference between a neutral expression and one
with a slight emotion.
So, I refocused the study on trying to figure out which facial feature most conveys emotions:
the eyes or mouth?
