Jeffrey Milstein photographs cruise ships in his series, “Cruise Ships.”

From water level, cruise ships can look like confounding, imposing towers—but in Jeffrey Milstein’s series of aerial photographs, “Cruise Ships,” the amazing designs of the floating behemoths seem clear and even beautiful. “Most of them have pools. They almost all have a putting green, a running track, a basketball court. The whole top deck becomes this kind of floating amusement park three football fields long. It’s an amazing construction,” he said.
