Minor issue; when I want a preview of a raw immage (such as adobe .dng) the preview does not show the true image, but has smeared colours. It does load fast.
A .jpg is looking and loading great, better details than before.

If in doubt refer to the developers website; Support/Help/FAQ/known issues/compatibility:
Adobe Digital Negative Converter
Contact a third party vendor

Thanks, I first saw it in safe mode. But first I will finish this presentation of some pictures, then have an extra look in safe mode again.
here is the original DNG converted to jpeg in Lightroom, and 1500x1500 size

You can see in the man on the right how a halo exists.
And here a page with previews in grid mode and two corresponding output jpegs. [see the other post]
So there look to be some parameters wrong here.
The inserts are again the jpegs in Preview, but that handles good.
In fact, I think jpegs are rendered much better than under Catalina. They look crisper. More details, more levers of colours.
The DNGs are originals from camera.
It would be nice if fixed. I do not like a unified skin colour on all pictures, nor halo's around persons . . .
You need to be asking these questions on the Adobe forums. All the software you mention is made by Adobe. The OS doesn't make this previews, the Adobe software does.
I'm afraid I have another position. It was always good in Preview. These are old files (60.000 of them . . ) . I noticed the Converter is of help because for a new camera I use it, and those previews are OK.
I think it is a Minor Issue; inconvenient.
My reasoning: the old Preview program read the files differently. And being software, it is easy to address.
Should I report a bug? How?
the pictures did not load so a new try
The experiment with adobe dng converter:
+1
First: the man in grey:
Now the strange thing. recent files, same camera, and here I found out what the issue is.
In the next example, the first one is converted DNG by Adobe DNG Converter after it came out of camera; the second one the image of the DNG as shown in the original state. And finally a created jpeg again of the same picture
This is again a grid view in Preview. The second image is the original, the first one converted to the same file. Evidently it has the parameters like Preview expects.
So as far as I see, the issue is that the new Preview from Monterey has some problems in the 'original from camera' version of a DNG file (in my case, Leica M); this has not been so before under High Sierra, Catalina etc. [I skipped Big Sur].
Handling it through the DNG converter can be done with new imports.
But not my 60.000 old files; I would be afraid my metadata would change or disappear and all changes and settings are lost.
It would be nice if fixed. I do not like a unified skin colour on all pictures, nor halo's around persons . . .
preview of .dng is not good in monterey
