My favorite exhortational photography story:

The photographer and curator Philip Brookman learned just how committed Frank was to making pictures. The two men were visiting Frank’s troubled son Pablo on Thanksgiving at a psychiatric hospital. Many families were there. At one point a patient sang a very clear and beautiful song she called ‘‘Sad Movie.’’ Brookman, moved, crept his hand toward his camera, but he worried that taking a photo would be inappropriate. As the moment passed, he heard a familiar, gruff voice: ‘‘You should have taken it.’’
