It's vignetting, probably because you turned on the OIS and misaligned the camera in the housing.
OIS? Are you talking about image stabilization?
PS: Tell your buddy to lay off the sharks. Interaction without touching is much more interesting. Use that whole mucous membrane stuff.
He was just an overzealous dude on the boat. I don't advocate anyone touching anything while diving, but you'd have to include me in the list of people who did that day. The sharks were very aggressive and on several occaisons I had to physically push them away.
You're right, those kinds of shots generally do nothing for a segment to say nothing of the fact that it's not healthy for either party. I only included those shots as examples of the footage. I'll take the link down now that a few of you have seen it to avoid further excommunication. Didn't mean to bum you guys out - sorry about that, folks. Unintentional but still a foul, I know...
I will definitely be careful about tightening down the camera to the tray in Australia next month. ANy other words of advice for this?
