This tab has been open for a while, so I’m not sure where it came from, but the astronaut gave a 30-ish minute talk at Luminance 2012 about the challenges and awesomeness of shooting in space.

It’s worth your time. For serious. Fun fact: hard drives fail quickly in zero-gravity, and nobody (to Pettit’s knowledge) has figured out why, so they transmit the raw files back to the ground as quickly as they can.
