"The Untitled Project" is a series of photographs of poeople and their real emotions.
Emotion, in its most general definition, is a neural impulse that moves an organism to action. Emotion is differentiated from feeling, in that, as noted, emotion is a psycho-physiological state that moves an organism to action. Feeling, on the other hand, is emotion that is filtered through the cognitive brain centers, specifically the frontal lobe, producing a physiological change in addition to the psycho-physiological change.
