Nikon D3S in Subal housing goes to Maldives tomorrow!

I am going to the Maldives tomorrow on a 2 week diving boat cruise aboard the Horizon III with my new Nikon D3S in a Subal housing and with the new 16-35mm f/4 for stills and video. Any suggestions for the setting for shooting videos with the D3S underwater? Have never done this before and would appreciate some feedback!

thanks

I shoot HDSLR video, but on a canon.

I shoot full manual.

I keep the ISO and shutter speed fixed and change the aperture accordingly. I have a RGB histogram that I check the levels with (on my 15mm) as exposure can be a bit tricky on such a wide lens, focus on the area and shoot. My video shots last between 3 seconds to about 30 seconds.

I recently dived with a chap with a D3s in a Subal... impressive bit of kit!

That depends on you Juerg. Since the D3s doesn't have a full manual mode IF I remember correctly, you have to deal with the camera choosing shutter and ISO. You have to set the camera to Tripod mode and use Av mode to set aperture to anything above f7 for the 16-35. The corners will be a bit soft @ f7.1 but at least some things will be in focus. Focus about 1.2m away from the dome port for 0.6m to infinity @ 16mm @ f7.1

What you have to do is trick the camera to lock shutter speed at 1/50 while @ f7.1 then use AE/L to keep that setting. But the camera will shift ISO to whatever it's metering. Forget WB as it's Auto as well

Good luck!
