DSLR Settings for Blue Light

[Travillion]

Hey all,
Just hoping someone can chime in on what settings they go with on their DSLR's when shooting under blue LEDs, like moonlighting. I'm having a hard time picking up any colour besides blue, can't even get anything from the fluorescent zoanthids. I'm shooting with a Nikon D3200, 18-55mm and 50mm 1.8. I am quite knowledgable with settings so feel free to throw anything at me.
Cheers!

I shoot using a dslr as well. What I do is use a white card under the lighting and then set a custom white balance.

Perfect, thank you Tim. I think I was just a little confused with Nikon's terminology. To customize their white balance it is labeled as "PRE" in the quick settings bar.
Once again,
Thanks for your help!

Hey Tim,
When you use the white card under the blue lighting, do you not get a disrupting shimmer effect in the water? Could I take a picture of the card out of the water with the same lights on it and still get quality photos in the tank?

I didn't get a shimmer because I turned off all the pumps so there was no surface agitation.

It would depend on the colour of lights you use and the depth of the tank.

I used a Xyrite Colour Checker and shot down on it. The one I got is water proof. It was in about 6" of water off to the side of a 400 watt Radium. Make sure your exposure is correct as it will effect the colour of the shot. Fill the frame with the target.

I just shoot raw and set WB to 20k in photoshop, sets color perfectly.

I heard they use Photoshop for shooting people in the raw.
