Custom made X-Rite ColorChecker DCP Profiles don't show up in Lightroom Classic 12.4

I'm really out of ideas ... I recently returned after approx. two years to my X-Rite Color Checker Passport to create custom DCP profiles for several of my cameras (to synchronize their colors when using them at the same occasion). Usually it was as simple as that: Create the profiles with the ColorChecker Camera Calibration software, place the resulting DCP-Files in C:\ProgramData\Adobe\CameraRaw\CameraProfiles (got a windows machine), restart Lightroom Classic - and the profiles could be chosen in the Profile Browser (Develop module) if you opened DNGs from the cameras the profiles were created for.

 

Forcing LR CC to read all new profiles from the File - Import Presets Dialog only results in the message that all profiles are already imported, so no solution here.

 

One thing to consider: The X-Rite Software version is the latest (Color Checker Camera Calibration version 2.2.0), but it is two years old (version is from July 2021). Newer updates aren't available. In the worst case the profiles created with that "old" piece of software don't match requirements of LR CC 12.4, but I sure hope that isn't the case.

 

Per default the X-Rite Color Checker Camera Calibration Software saves the created DCP profiles in C:\Users\[Username]\AppData\Roaming\Adobe\CameraRaw\CameraProfiles. But it doesn't help at all if profiles are imported from there - same result.

 

Another thing to consider is that the X-Rite software doesn't seem to be able to differentiate - at least as far as naming of the profile is concerned - between DNGs generated from the same device but from different cameras of that device (talking about a Google Pixel 7 Pro here with its four sensors and lenses = four cameras). At least it tries to save DCP profiles for all cameras under the same name (but appends a hyphen and a number if it discovers that the standard profile name is already in use).

 

The Adobe standard profiles that are located in C:\ProgramData\Adobe\CameraRaw\CameraProfiles\Adobe Standard on my Windows machine differentiate between those four cameras of the Pixel 7 pro and provide different DCP profiles for each of them.

 

That all said a freshly created ColorChecker DCP profile for my Ricoh GR - that definitely has only one sensor and one lens! - doesn't show up either in LR CC.

 

I'm really out of ideas - any thoughts how to get those profiles visible so that I can choose them within LR CC? Would be very welcome indeed!

I think it does explain that. The XRite software probably saves the profile with specific camera information, for example with what Lightroom shows as lens information. That means that what Lightroom considers lens metadata might be what the profile uses as camera metadata. Which means that none of the profiles match the 'Pixel 7 Pro' camera metadata that Lightroom sees. Or do you mean you can't create a profile for a totally different (normal) camera either? That is not my experience.

 


I think Johan's explanation is correct here. The X-rite software is likely not including the correct camera metadata in the dcp file for it to be recognized by Lightroom. Not much you can do here since the passport accompanying  software is no longer being maintained it appears and hasn't been for many years. Adobe also dropped support for developing their profile creation software many years ago so it seems there is no good way to do this anymore. I guess you could use dcptool (https://dcptool.sourceforge.net/Introduction.html ) to decompile the dcp files and edit the camera descriptions to be correct and recompile them in principle. That could work but will take some tinkering.

Sorry, wrong topic headline - my custom profiles don't show up in Lightroom Classic 12.4 - I don't use the cloud-based Lightroom.

Corrected the title.

Can you select ICC versions for the profile? If yes, make sure to try with v2 instead of v4.

I don't know but I think it's likely that the XRite software does not 'see' the different cameras of that phone. This software was probably written before the first phone with multiple cameras was introduced. As a result, the DCP profile is probably not correctly linked to the phone, and that is why it does not show up in Lightroom. Just like Canon profiles won't show up when you select a Nikon raw image.


Thanks, Johan, for your reply. It's possible, but I'm not completely convinced that it is XRites fault. Phones with multiple cameras are not new, and the last update of the XRite software is from July 2021, so it's not that old. Also the EXIF info available in the DNGs should link the custom profiles automatically to the corresponding profiles as far as I understand it. 

 

Don't forget that it's quite irritating that there are two profiles of unknown origin in the "Profiles" section of the profile browser for the Pixel 7 Pro that seemingly can't be removed by emptying the folder where custom profiles are stored. And that those profiles are somewhat generically called "Google Pixel" - no indication that they are specifically meant for the Pixel 7 Pro. Add to that the irritiating (and very off) color mappings of the Adobe Standard and "Google Embedded" profiles also available for it - all that makes for a less than enjoyable experience handling the Pixel's DNGs with Adobe products.

All this looks like a metadata problem. Lightroom links a profile to a camera by comparing the camera metadata in the image to the camera metadata in the profile. If they match, then that profile is shown. This phone should appear as four different cameras in Lightroom, depending on which camera was used, but it sounds like maybe it doesn't.
