IMHO That setup is for a very specific task. Like enlightening a big animal in blue shallow water in sunlight or similar.
I would never use that setup for a plain wa shot.
Shadows are your best friend not your enemy.
I would give extra light to my buddy asking him to light everything from above. You get a dramatic effect like 3D with increased DOF.
If no buddy is avail then place all your lights as close as possible and move to enlight from above emulating sunlight.

David, I agree with your point of view. What do you mean by the last part “ light from ABOVE emulating sunlight”?

I have just started experimenting with 4 lights so my experience is really limited and don't even know if i am using them the right way. I actually searched online for guidelines but was not able to find something.
Anyway i am using the two Keldans mounted on long arms at the handles ball mounts and the two sea dragons mounted directly (no arms) at the left and right tripod ball mounts of the Nauticam GH5 housing. I was having the sea dragons positioned parallel to the housing. Next time i ll try to mount them on short arms and position them lower that then housing. That might work better for wide angle shots away from the bottom. Of course there is no recipe covering all scenes and only with experience might get somewhere meaningful. 
Any advice would be highly appreciated with someone having more experience in using 4 lights


Thank you for your prompt reply. I have no experience with 4 lights and I hope somebody with experience adds value to the discussion.
Is the purpose of 4 lights to have a wider beam for wide angle coverage or is it get rid of shadows (usually) casted by 2 lights?

And another one from a recent dive on a small wreck.
Depth is between 36 and 40 meters. Vis was around 10 meters but with lots of suspended particles.

Thank you for sharing. How do you position the 4 lights?

Cant agree more if one is shooting full frame video. Youd need 9 dome to support such wide lens. The challenge with such setup for video is ergonomics but again this is subjective.
By the way, this is not a G Master it is a G series Sony lens.
