I didn't have an underwater camera since I was filming the topside shots, so I had to be very careful not to damage it. As soon as you put a camera into an underwater housing, it's more restrictive. It gets really heavy. So, I held a large broadcast camera above the water and was directed by people on the boat. We had some DSLRs on board, as well as some Sony cameras and a Panasonic Vari Cam for the high speed footage.
