“You don’t identify the poseur by which pose he is copping, but rather by the participle, by the act of posing itself. A poseur can be smiling or glowering for any number of cameras. He might be a New Testament scholar, a gym rat, a hipster, a poet, or a smooth ladies’ man. He might be any number of things. We do not identify him by the costume he is wearing, but rather by the fact that he always has one eye on the lookout for a camera or a mirror.”
