"One thing that Wall knew for certain when he took up the profession in the
late 1970s is that he would not become a photojournalistic hunter. Educated as
an art historian, he aspired instead to make photographs that could be
constructed and experienced the way paintings are."
Photography seems so accessible as a viewer and as a creator because we consider that there's an element of luck (in addition to patience and having a good eye). But where Jeff Wall has taken the photograph is to a place where the artist's vision is as important as it is in other artistic media. He does not see the picture in front of him; he creates it.
The Times Magazine also features the home (and contemporary art collection) of philanthropist Constance Caplan. The article doesn't say where in Baltimore this is, but I think it's way north, by Lake Roland, possibly in Baltimore County.
