Garry Winogrand said, "I photograph something to see what it will look like photographed."
Surprise is another essential ingredient in a photograph.
Humans love surprise, from our earliest encounters with it while playing peek-a-boo, to looking at photographs.
The term encompasses the many types of surprise, including the following.
• Great light
• Movement or stasis
• Harmony/order/stability/balance, or the opposite, such as Koyaanisqatsi, a film about life out of balance
• Formalism, geometry, composition, tone, color
• Seeing something in a photograph that would cause a PET scan of our brain to light up with our own memory, commonality, anti-ness, fear, lust, or ?
• Seeing something that we would ordinarily have passed by without notice
• Being taken to a place/mood/context that we wouldn't ever encounter otherwise, such as an emergency room floor after the treatment of a gunshot wound (Eugene Smith) or "Skips First Shot [of heroin]" (Larry Clark).
• Time is frozen, sequenced, squandered, and ?
• Knowledge that a person made the photograph, while at great risk.
• In the case of a daguerreotype, that the plate was present, in the camera, and the light from the subject touched the plate that is before you.
