Between 1917 and 1937, Alfred Stieglitz (more) shot over 300 portraits of Georgia O’Keefe (and he was married to her). Stieglitz believed a portrait needs to be more than just the face to portray the subject’s overall experience.
"Stieglitz had a very sharp eye for what he wanted to say with the camera… His idea of a portrait was not just one picture. His dream was to start with a child at birth and photograph that child in all of its activities as it grew to be a person and on throughout its adult life. As a portrait it would be a photographic diary." -Georgia O’Keefe
The last photo of Georgias hands was sold for $1,470,000 in 2006. And is one of the most expensive photographs sold.
