One example of benefiting creatively from working with constraints. Back in the 1980s, I read a comment from a newspaper sports editor that went something like this -- "Back when sports photographers used the big 4x5 Graflex camera, a guy would go out to a game with 5 plates and come back with 5 usable shots. Now guys use motorized 35 mm cameras, shoot several rolls, and often come back without a single good shot."
