For those ground pictures, McArthur Velcroed one 760 body with a 180-mm Nikkor lens beside the window in the U.S. lab module. He used a second one with a flash attachment to record experiments, often in intervalometer mode. "Near the end of the mission I tried to take pictures of every square inch of the station because it's a great value for folks on the ground -- the condition of the equipment, how we had things laid out," McArthur says. Two other bodies are attached by a frame to the chest of extravehicular activity (EVA) suits, covered with thermal blankets against the cold of space. Again, the subject matter can be unusually banal: documenting the bolt-by bolt installation of a new gyroscope, maybe.
