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. “Most photographs cannot get looked at very often,” he told me. “They get exhausted. Great photographers have done it on the fly. It doesn’t happen that often. I just wasn’t interested in doing that. I didn’t want to spend my time running around trying to find an event that could be made into a picture that would be good.” He also disliked the way photographs were typically exhibited as small prints. “I don’t like the traditional 8 by 10,” he said. “They were done that size as displays for prints to run in books. It’s too shrunken, too compressed. When you’re making things to go on a wall, as I do, that seems too small.” The art that he liked best, from the full-length portraits of Velázquez and Manet to the drip paintings of Jackson Pollock and the floor pieces of Carl Andre, engaged the viewer on a lifelike human scale. They could be walked up to (or, in Andre’s case, onto) and moved away from. They held their own, on a wall or in a room. “If painting can be that scale and be effective, then a photograph ought to be effective at that size, too,” he concluded.
