Surprise is the most fleeting of all emotions. The distinction between real surprise and false surprise helps differentiate sincerity vs insincerity. If apparent surprise lasts more than a few seconds, there is at least a component of it that is false or exaggerated. It's almost always is followed by a second moderate to strong emotional response - commonly anger, fear, embarrassment, laughter, relief, or disgust. Here, Aiden Grimshaw (of The U.K.'s X Factor fame)is experiencing fear after initial true surprise. Because surprise is so brief, photos of pure surprise are rare, and most of those examples are blended with another emotion - as demonstrated here with Mr. Grimshaw. Both surprise and fear cause the eyes to be opened very widely - which I call "White and Wide", and with the additional bearing of Aiden's teeth (especially his bottom teeth) in the context of a dropped jaw and a widely open mouth is a sure signal of an of element fear rushing in.
