A while back I posted a skin tones comparison featuring the Nikon D300, D700 and D7000. I was told I needed to use a real Caucasian subject, and after much searching, I finally got one to agree to pose for me. At issue here is whether the Nikon D7000 struggles to render accurate or complimentary skin tones.
To get started, let’s see how these cameras compare under controlled, constant lighting, using the same exposure and lens. All three shots were captured using each camera’s Auto White Balance (WB) and Portrait Picture Control, then converted from RAW in ViewNX, which essentially results in a JPG the camera would have produced with those settings.
1. As shot, with Auto-WB, converted in ViewNX.
Next, since each of these shots conveniently features a Colorchecker chart, a WB adjustment by sampling the middle gray patch is possible. These next 3 versions of the photos reflect the adjustment.
2. WB adjustment in ViewNX
At this point, any sane person would stop, noting that the differences from one camera to the next are trivial and hardly worth the trouble. Just for kicks, though, let’s see what we get in Lightroom, using each camera’s Portrait profile — an emulation of the Portrait Picture Control.
3. Lightroom conversion using Camera Portrait profile
Since Lightroom might not bring across the Auto WB setting from the camera, we can once again sample the color chart’s gray patch to adjust the WB, giving these 3 versions of the photos. Curiously, it is the D700′s photo which now deviates most pronouncedly from the others.
4. Lightroom with WB adjustment
For the final set of shots, I used Dual illuminant profiles I generated a while back using the same Colorchecker chart and DNG Profile Editor. After applying the same tone curve to all three shots and adjusting exposure for the D700 shot, we get the next 3 shots.

I’ll let you decide on whether these improve on the previous results (the jacket is supposed to be purple rather than red), or whether the D7000 struggles to produce pleasing skin tones. I’m going back to doing the sane thing.
