Nikon original colors for Capture One - D2XMODE

There are a few generation of color modes that were implemented consistently by Nikon developers in digital cameras: CCD-sensor cameras, Nikon D2X, Picture control, Latest Picture control.

In my opinion color modes for CCD-sensor and for Nikon D2X tried to be closer to the traditions of color film.

There were developed D2X color modes in form Picture Control: D2XMODE1, D2XMODE2, D2XMODE3 for Nikon D3, D300, D700.

For cameras released later support of color modes D2XMODE has stopped. In “Nikon original colors for Capture One” I told that I have idea how to make D2XMode icc profiles for these cameras.

My method is quite simple.
It is necessary to measure shift of color values between my NikonD300-EO-NXD-Neutral.icc and NikonD300-EO-NXD-D2XMode1.icc profiles.
Then this measured shift is necessary add to my Nikon[CameraModel]-EO-NXD-Neutral.icc and get Nikon[CameraModel]-EO-NXD-D2XMode1.icc.

To check it, in the studio I has took a photographs of color target with my Nikon D300 and with rented D5100.

Reference: NikonD300_CC_NXD_D2XMODE1.tif developed in Capture NX-D, picture_control: D2XMODE1, noise_reduction: off, all_another: default, tiff: 16-bit AdobeRGB

Sample: NikonD5100_CC_C1_D2XMODE1.tif developed in Capture One, base_icc_profile: NikonD5100-EO-NXD-D2XMode1.icc, base_curve: Film Standard, sharpening: No, noise_reduction: disable, all_another: default, tiff: 16-bit AdobeRGB

RGB-values of patches obtained with Argyll scanin.exe:
NikonD300_CC_NXD_D2XMODE1.val
NikonD5100_CC_C1_D2XMODE1.val

LAB-values of patches for D50 illuminant were obtained from RGB-values by calculation:
NikonD300_CC_NXD-D2XMODE1_LAB16.txt
NikonD5100_CC_C1-D2XMODE1_LAB16.txt

Then I compared these files using X-Rite MeasureTool Utility:

NikonD5100_CC_C1_D2XMODE1_DeltaE2000-16.txt describes detailed results.
Worst Delta E 2000 = 2.97

This is good result for NikonD5100-EO-NXD-D2XMode1.icc.
It confirms that the method works and I can make D2XMODE1, D2XMODE2, D2XMODE3 icc profiles for Nikon cameras that originally do not have them in the cameras picture control kit.

Remark:
In fact, the accuracy of the profile obtained is even higher.
The quality of the experiment was negatively affected by at least two factors.

First:
Nikon D5100 does not allow to set WB as Color Temperature. So I set WB->[Direct Sunlight] on both cameras. At the same time, it has turned out that the WB values for cameras was a little different.

Nikon Capture NX-D

Capture One

I think the influence of such a deviation is negligible.

Second:
Although the exposure settings were the same for both cameras, and the same lens was used, subsequent comparison of neutral patches required an exposure correction of -0.22 for the Nikon D5100.

And this influenced the accuracy of the experiment.

But at the time of processing the files, I already returned the D5100 and could not repeat photographing the color target again.

And finally an example from the real world:

Nikon D300, Nikkor 50/1.4D

Nikon Capture NX-D, picture_control: D2XMODE1

Nikon D5100, Nikkor VR 18-55/3.5-5.6G

Capture One (Phase One A/S), icc_profile: NikonD5100-EO-NXD-D2XMode1.icc, base_curve: Film Standard
