Colour issues with TG5 and lights

27 November 2017 - 03:19 AM

i recently purchased an Olympus TG5 after using a TG1 since its release.  I didn't have much time to play with it before our trip so pretty much stuck it in UW wide or UW macro.  I use two Hi-max video lights which are very bright (so much so I mostly frighten the fish). 

 

Been sitting trying to thin out my videos and really wishing I'd spent some time on holiday looking at the files while we were there.  Everything, including the shallow reef stuff is BLUE!  Even in 5m of water, it's very blue and when I try to correct I end up with very flat "beige" footage.  

 

Here are a few examples:

 

Octopus: shot with video lights, less than 15m and vectorscope of image as shot

Fixed image and vectorscope:

Turtle shot with video lights at less than 10m. 

 

LHS uncorrected; RHS corrected

Corrected image and vectorscope:

I think I know what has happened, I think my lazy use of the UW mode has pretty much cancelled out my video lights.  Or the lights have confused the sensor.  I'm not sure what WB mode is best for UW with lights, the old TG1 wasn't quite so sophisticated as the new camera.

 

Any ideas on how to rescue the flat looking footage?  Or what is the best setting for UW video with lights on a TG5? 

 

Thanks
