How do I get the blue spectrum from flooding the pics?

I am using 12K MH bulbs. The blue seem to flood out every pic.

Using a Nikon D70 with 55mm lens and auto settings for now.

In the old days, you could try warming filters. But with the advent of digital, you do everything in the digital domain. You will need to fine tune your Nikon D70's white balance until it is close to the color result you are looking for, then do the final manipulation in post process (with programs like Photoshop). Lens filters are a lot more expensive and difficult to get right.

What Len says. Find a piece of white or 18% gray plastic, stick it in your tank, and do a custom white-balance off of it. I pretty much start every shoot with a gray-card shot.

And shoot RAW...lots easier to fix white balance issues than with a jpg.

Thanks guys I'll give it a shot. I thimk I got in over my head with this D70. I will do my best to pull it off.

if you have a copy of photoshop, go to "new adjustment layer" then "levels" then "auto" and then "OK". This will elimainate your colour cast.
Good luck!
