As Wayne and Garth would act out, their fingers going from raised to lower, saying "doodle do doot, doodle do doot." Hit the fast forward button now 50-75 years into the future. Lets look at Richard Avedon and Annie Leibovitz.

Manipulation was a charge that was often leveled against him. (Avedon)There is
an often-told story that when he had the Duke and Duchess of Windsor in his
studio they started out the session putting on their best royal faces, the
public masks that concealed their private despair. If they thought they
could
get away with this practiced deception, they were up against the wrong
photographer. Avedon told them a lie that would shatter their defenses,
namely
that his dog had just been killed by a taxi. The resulting look of
horror and
grief destroyed their protective coating, because, as Avedon
himself put it,
"they loved dogs more than they loved Jews." Is the
resulting image an accurate
representation of their inner selves?

Annie Leibovitz, many years ago, did a series of American Express commercials. One of her models was John Elway. I remember reading an article about the encounter and how Leibovitz had come into town 24 hours earlier, simply to get to know John so she could depict him as he was. As John had a ranch and he was a Bronco, one thought was to go out to his ranch and photograph him in western garb. The day of the shoot, it started raining. To make use of the time she did some indoor portraits of John from the waist up, without a shirt, holding an infant daughter. Rather than telling the subject how she felt or thought they were, she allowed the subject to tell her.
