Does anyone know where the magic button is to change the white balance? My images all have a yellow ish tint to them.. The little white balance metter just makes it more prounced in the other color bands.theres another menu that I can change the monochrome of a image. How do I actually get it to a picture of what it sees? Can it be my light source? I am using white lights

Our eyes will compensate for different light sources, but on cameras it needs to be set manually (if auto doesn't look good). On some Nikon cameras, white balance is set by a control on the body. On yours, it's set in the menu screen. Here's p. 87 of your manual.

The best way I have found is to use the RAW .NEF files and leave the image processing to software, not the camera (I use Photoshop CS6 here, but other software, including software from Nikon are just as capable). The camera will save the light temperature in the .NEF file, as well as shutter speed, F-stop and other information.

You get the most flexibility shooting in RAW, provided you have the software to work with it--another CS6 user here. Of course, it can't hurt to get the WB right in the camera--less work in ACR that way.

I think WB is much better--the metal tone is more neutral. It's still a little high in yellow-green, but you could tweak that easy in software.

Make sure your background is a non-reflective black or dark gray.
You want the light your camera collects to be as much from the coin as possible.

Not to mention, a monochromatic background makes it a ton easier to know if you got the color right. Don't look at the coin, look at the background to check color. If the background is right, the coin is right - at least to the extent that the camera sees it under the lighting conditions you've established. And this can "alter" the apparent color of the coin, leaving you beating your head against the wall trying to get the color right when it's the lighting arrangement and not the White Balance that's the actual problem.

What's the actual background color for that shot? And is there any reason why you aren't using a Custom white balance setting?

And it's easiest to tell color casts in neutral mid-grays. I could make a plug for the LAB color space here and mention it's really easy to determine (and correct) color casts in that mode.

Or you could just use a Custom white balance setting and never have to care about color again. I just don't get why people don't do this. It's as elementary as focusing the shot.

That works too--if your lighting is very controlled, not affected by time of day or different color temps leaking into your scene.

If your lighting is changing so quickly that things change between the time you do manual white balance and then snap the shot, you need to work on a different lighting arrangement.

I'm more talking about setting a custom WB--then going with that for extended shoots w/o adjustment.
Course, this is coming from someone who does lighting setups--but mostly natural light, where light temp changes with cloud cover here.
But anyway...not trying to be acrimonious here--I'm just super detail-oriented.
