Two things can be said for Kienitz. First, defendants did not need to use the copyrighted work. They wanted to mock the Mayor, not to comment on Kienitz’s skills as a photographer or his artistry in producing this particular photograph. There’s no good reason why defendants should be allowed to appropriate someone else’s copyrighted efforts as the starting point in their lampoon, when so many non-copyrighted alternatives (including snapshots they could have taken themselves) were available. The fair-use privilege under §107 is not designed to protect lazy appropriators. Its goal instead is to facilitate a class of uses that would not be possible if users always had to negotiate with copyright proprietors. (Many copyright owners would block all parodies, for example, and the administrative costs of finding and obtaining consent from copyright holders would frustrate many academic uses.)
Second, this use may injure Kienitz’s long-range commercial opportunities, even though it does not reduce the value he derives from this particular picture. He promises his subjects that the photos will be licensed only for dignified uses. Fewer people will hire or cooperate with Kienitz if they think that the high quality of his work will make the photos more effective when used against them! But Kienitz does not present an argument along these lines, and the consideration in the preceding paragraph is not enough to offset the fact that, by the time defendants were done, almost none of the copyrighted work remained. The district court thus reached the right conclusion.
