Blue Hue

[Spartan]

Hopefully this is an easy thing...

My tank is lit by 14k MHs. When I take nonflash photos, they have a much bluer hue than the tank looks in reality. How do I fix that with camera settings? Or is this something done in post processing?

white balance on camera.

take a part that is supposed to be white, like sand and use that as the reference. or grey ...


but if the camera allows, its best to take the pics in RAW, and then change the white balance on a computer after. you would be able to get much better images and balance the colors better that way.
