“He was so authentic, in a way that a lot of us had never experienced,” Mr. Burns said. “You wanted to be like him. You wanted to tell the truth. You’d go out to take pictures with him, and we all saw the same things he did, and then we’d come back, and he’d put up his prints, and you’d put up yours, and you were devastated.”

He added, still seeming to wince all these years later at the memory: “Sometimes you’d do some work you thought was really great, and you’d show it to him, and he’d stand there for a while and then say, ‘Well ...’ And it was like, ‘Oh God.’ That was all it took. That ‘well.’ You knew you hadn’t done it.”
