Adams believed that photography was about interaction. He often compared the negative to a musical score and the print to its performance. It was Adams's view that: "The picture we make is never made for us alone; it is, and should be a communication to reach as many people as possible without dilution of quality or intensity. . . . To the complaint 'There are no people in these photographs,' I respond, There are always two people, the photographer and the viewer."
