Astronaut Don Pettit doesn't have the name recognition of Ansel Adams, but his work literally transcends cultures and borders around the globe. Pettit is the photographer behind the amazing time-lapses coming from the ISS, and here he is with all 10 of his cameras.
You might be wondering what he's doing that requires all this equipment. Well, it has less to do with "needs" and everything to do with weight. Whenever a new camera is sent to the ISS, it either stays there or must be discarded before re-entry. This is because of strict, re-entry weight limitations which don't account for giant DSLRs and their sometimes even larger lenses. All this adds up to a lot of cameras over a long time and a lot of incredible footage. [OnOrbit via Petapixel]
