Guide to create DCP Colour Profiles for DXO PhotoLab, Lightroom and Photoshop
3

I know others have probably posted similar, but I wrote this guide for anyone that needed further info:

:

Download Adobe DNG Converter here:

https://helpx.adobe.com/au/photoshop/using/adobe-dng-converter.html

Install DNGConverter_11_1.exe

Download ColorChecker Camera Calibration software here:

https://www.xrite.com/service-support/downloads/c/colorchecker_camera_calibration_v1_1_1

Install ColorCheckerPassportSetup, and select Desktop ColorChecker Passport when prompted.

Goto the DPReview Studio shot comparison page:

https://www.dpreview.com/reviews/image-comparison

Select the Required Camera from the drop down list.
Select RAW and the lowest ISO.
Rightclick the blue RAW link, then Leftclick "Save target as" and save the RAW image.

Run Adobe DNG Converter, then convert the downloaded RAW image to DNG.

Run ColorChecker Passport, then Drag&Drop the DNG file into the window.
Click Create Profile, then save the DCP file to the default directory.
Note: the default directory is usually \AppData\Roaming\Adobe\CameraRaw\CameraProfiles

Run Lightroom or Photoshop, and select the DCP profile in the Color Profile Browser.

:

If you are using DXO PhotoLab, copy the DCP file to the following directory:

C:\Windows\System32\spool\drivers\color

Then in DXO PhotoLab, select the images you wish to process, then goto the Customize Window.
Select Color Rendering, choose Catagory - DCP profile, Rendering - the required camera DCP, Intensity = 100
Export as required.

Re: Guide to create DCP Colour Profiles for DXO PhotoLab, Lightroom and Photoshop

That is interesting, how accurate is this method compared to one using the x-rite passport ColorChecker and making a camera profile? Too bad they don’t have RAW for the iPhoneX or Xs.

I find it very accurate.

Try it for yourself, then let us know.

I’d love to but I have an iPhone X and XsMax and there was only JPG, no RAW on that image comparison page for iPhone X.

Re: Guide to create DCP Colour Profiles for DXO PhotoLab, Lightroom and Photoshop

Den, thanks so much for posting this concise guide.

I have bookmarked this thread, so that when I venture into DCP profiles, this will be a prime reference.

Might have a question or two for you, before long...

What's the difference between ICC Profiles and DCP Profiles may I ask?

Re: Guide to create DCP Colour Profiles for DXO PhotoLab, Lightroom and Photoshop

This is great info, so it seems iPhone users would need to purchase a ColorChecker passport and follow the steps to create the DCP. (Adobe’s DNG converter v11.1 supports even XsMax)

Or find RAW files including a color reference as in the image comparison page?

Yes, if you can find a iPhone RAW image with a ColorChecker chart in the shot.

Or just buy the X-Rite ColorChecker Passport and create the profile yourself.

Does this work for PhotoLab 1 as well, or only for v2?

Unfortunately not, DCP support was only just announced for DXO PhotoLab version 2.1

Thank you Den! Saved for later when I'm more awake and have higher brain function.

Two Questions....

Den,

If I'm reading correctly , you are saying the DPR test image, converted to DNG, can serve in place of  a DNG shot by my camera?

Would the resultant DCP be as accurate or faithful as a DCP generated using a DNG shot from my particular camera copy and an X-Rite Color Checker target?

Thanks in advance for your replies,

To build a .DCP profile? No. I mean you could, but the entire point is to build a profile based on your specific camera sensor.

Would the resultant DCP be as accurate or faithful as a DCP generated using a DNG shot from my particular camera copy and an X-Rite Color Checker target?

No.

Thanks in advance for your replies,

FWIW, I found existing custom profiles I built for my various cameras imported fine in this product. I can't nor should comment on 'accuracy' because that's not pertinent but I can say, like Lightroom or ACR, my own profiles provide a more pleasing color rendering than existing profiles. Which is why you want to build your own profiles from your specific camera(s) in mostly different types of lighting (daylight, tungsten, Fluorescent etc).

Just to add -- when one uses the same DCP profile in both Lightroom and PhotoLab2, and disable all there is to disable in both converters, and then output the files and compare, there will be (at least) 2 slight differences that can be noticed by eye. One is the white balance -- each raw converter calculates white balance differently. The other is contrast -- DxO applies a different black level subtraction than Adobe , which results in more contrasty shadows and highlights. But the hues look pretty similar, if not exactly identical.

I'd fully expect that.

One is the white balance -- each raw converter calculates white balance differently.

I'd expect that too considering the values provided in Kelvin are a range of colors and each converter will interpret them differently.

The other is contrast -- DxO applies a different black level subtraction than Adobe, which results in more contrasty shadows and highlights. But the hues look pretty similar, if not exactly identical.
