In my workflow I am usually using DxO Photolab only to apply noise reduction and optical corrections, then export a DNG and continue work with a different software. I am using a 14" M1 MacBook Pro running Monterey
After the upgrade to PL6, I noticed that the colours (especially reds/browns) in the exported DNG are often over-saturated, and do not look like they have been displayed in PL.
I narrowed it down that this happens only if I am using the new “Wide Gamut” colour working space, and then export the image using the “Export DNG (Denoise & Optical Corrections only)” action.
Here’s an example that shows the embedded thumbnail of the original RAW, and the result of different combinations of color working space, and export actions:
Thanks for the tipp regarding putting camera / platform details into the name, I didn’t think of that.
I haven’t been using any noise reduction in these examples, so it shouldn’t be related to DeepPRIME.
I searched for dng export & colour topics and found these two threads:
This one contains much more details
But even after reading those, I don’t understand if my specific issue is expected behaviour (and I don’t just understand enough about color spaces), or if this is an issue worth reporting.
In the second thread, @Barbara-S explains that " If you export a DNG using PhotoLab and you open that DNG in PhotoLab, you shouldn’t see a difference."
The WideGamut_OpticalCorrectionsOnly.dng file that you see in the screenshot above,also has that saturated reds/browns (which aren’t present in the preview) when its displayed in DxO (after the export). All other exported files look exactly as the preview PL6 shows before exporting.
So far, all my testing has shown that exporting DNG in ‘wide gamut’ will shift the colours and there is unusable.
Even if opening the same DNG in DxO, you’ll see the same colour shift.
My ticket about this - yes, I opened an official ticket - has been silent for almost a month now.
My question still is: ‘is this expected behaviour. If it is, how are we supposed to use those files in other tools?’. And if it isn’t expected behaviour, can the ‘gamut’ option be ignored while exporting DNG, so you don’t leave it on the wrong setting by accident.
