I've noticed that my D70 has started to render some black colors in my pictures as brown. I'm shooting under studio lights and checking the exposure with a light meter.
The shots look super except that some black fabrics (velour skirts and wool sweaters, eg) render dark brown. If someone in the same photo is wearing black leather shoes or a black cotton t-shirt, those are black.
I'm adjusting it back to black in Photoshop, but would like to adjust the camera or have it serviced if needed.
Any thoughts? |

Two thoughts:
1 - maybe it's a white balance issue?
2 - what we (people) see as black with our eyes may not be black to a camera, especially in comparison with other blacks (since you mention cotton fabrics looking brown compared to black leather boots, cotton fabrics tend to have softer colours than leather, and the blacks are often not "as black" as we wish they were.
Hope that helps! |

So true. How many people think that zebras are black and white? They aren't. Zebras are white and brown, but because of the high contrast ratio they look black. If you ever have the chance to get with in about one foot of a zebra you will see it. I'll post an example.

OK, I'll buy that it might be a white balance issue. But I'm having a hard time as to why some blacks are black and not others. Take a look at this image. Shoes and pants are black, but all the shirts came out brown. And the shirts did look black.
Thanks for the responses!!

Hmm.... this looks like a saturation issue that I experienced when I first got my D70. Are you shooting RAW or JPG? If JPG, then the White Balance is color correcting thinking that those reflected lights (on the shiny velvet/wool) should be in the red range.
I did a factory reset of my camera (the tiny button on the bottom of the body) and then loaded the White Wedding Color Curve by downloading it and the trial version of Nikon Capture. Most of my blacks are now truer unless I'm shooting High ISO or very low light low ISO (noise).
Stop by www.nikonians.com hit the D70 forum and search white wedding curve. That will lead you in the right direction.
If you are shooting RAW, the curve does correct some color imbalance as well, but you need to make sure that you have the latest Photoshop Camera Raw plug-in (2.3 I think) and may need to tweak the red shift on the Advanced tab.

| Yeah, I'm shooting jpegs. I'll try resetting and downloading the curve and see what happens. I appreciate your help. |

I love the White Wedding Curve also! definitely brings out the midtones a lot better than the default. I think you have to have that stupid Nikon Capture 4.(1?) TO UPLOAD IT THOUGH. THAT IS WHAT SUCKS!

Actually, you can D/L the trial version, upload the curve to the D70, then uninstall NKCap. ...although, sometimes I wonder if I should have saved the money on PScs and just bought the NikCap.
then again, could just be the new PC I'm on and the 5 days it has taken to finally get the LCD profiled and color corrected.

Yes, you can use it for 30 days...what happens when you want to try a different curve...or your own? That is what gripes me. Have to start looking for an alternative...gotta be a hacker out there doing it by now. (C:

Yeah, this is something I adore in Nikon marketing boys. You buy an expensive piece of equipment and to fully utilize it's basic functions, you have to pay some more to the same company. blah!

Is it perhaps an exposure problem most meters see things as 18% grey so if you have metered off something black you need to close the apeture down to render it as a proper black. Also the dyes in the clothing may not respond to the camera as the same blacks,

As kiwinick has started to say, it is a phenomenon you'll sometimes notice under blue light - certain dyes used to make fabrics black react quite weirdly under deep blue light, and can really look almost red to the human eye. What's happening in your shot is that the slight over-exposure necessary is just over-emphasising that effect in those clothes. In fact, it's that the clothes actually aren't black - they're a very deep shade of something else.
