 Thanks Sean,  that is Premier Lake.   I lie your idea to move the light so it is not inline with the viewing angle.  It would then be more like a street light.My camera is just a cheap thing, and I think I had my light angled down too much because the inside of the sub was lit up lol.  Neat trick with the white object in the gripper! Do you think the wind and waves can make the lake loose clarity in one day?Hank

 Good video Hank. What lake were you in?

Also wondering what camera you were using inside the sub to film this? If it supports white balancing using a reference, one trick I have seen done is to hold a white tablet in the manipulator jaws with the arm extended, and then zoom in on that through the viewport / dome to perform a camera white balance and better restore true colour on video.

As far as lighting goes, one possible thing you could do to improve apparent clarity is to physically move your light sources outboard, so that they aim towards centre front at an angle, instead of being right in line with your viewing direction. This tends to minimize backscatter from suspended particles in the water.

 Cliff, sorry I managed to have it on the private setting, it should work now.  Ignore the dirty protection dome.  The travelling on gravel roads makes it super dirty.  I need to address that.  I am thinking also that I need to lower my light.  I have been blaming a storm for bad visibility, but I am not sure if waves and wind can effect the clarity that much?  Maybe my light is not sufficient?Hank

 Hank, when I try and run this video, YouTube comes back with a "Video not available" message.  Can you reload?
