White Balance?

Yes you have to shoot something white under the LEDs in the tank but most people have success using the sand bed for this. It's a pretty simple method and usually the only one for tank lighting if it's on the bluer side.

OK, thanks for the tip on how to set the manual WB. I did some more research, and will definitely have to give that a try.

I also tried playing with the exposure settings a bit, and that seemed to alleviate the LED effect to some extent as well. There are just so many options and combinations to try, so will probably just have to keep experimenting.

Good news, though, is I am very happy with the image quality and detail, when I do get it right. Being able to shoot underwater is a huge advantage.

Well, I tried the manual WB capture using the sand bed. Definitely making progress here now...

The below pic was taken with the new manual WB and the flash off. The LED purple/blue effect is now gone. If you compare this pic with the ones above, it is actually closer to the one with the flash on, and not at all like the flash off one. And I would say it is pretty close to the true colour of the coral now. It is an Ice Fields Tenuis, and the ice colour is now showing much better as are the blue tips.

There are more things I want to try to improve the image quality with ISO and aperture settings. But I think I have this WB issue fixed now.

Thanks again, sphelps, for your help. I definitely learned something...

With LEDs, provided you have dimmable channels, you can also tune the color temp to what works best for your camera. While we might prefer more blue for our eyes, pictures usually come out better with whiter light.

I have the Radion LEDs, and yes, could do that as well. I could dial the blues down all the way for pic taking. I was surprised how well the sand bed worked, though. I didn't have anything else white handy, that was suitable for underwater.

But am satisfied with this for now, and will keep experimenting. I am starting to like the new camera more and more.
