DNG - uncompressed or new high fidelity

@Coldcoffee-101 Which is what you had in v4, so you didn’t really “lose” anything by upgrading, i.e. status quo.
Yes, agreed - but I never said I lost anything either, I said I couldn’t take advantage of the new feature & asked politely whether that was something the devs would be looking to fix/add
Sorry, I guess misread into this as a regret/complaint about your workflow breaking totally.
Already transparently tracked in GitHub:

@kmilos - this is great but it sounds like the effort is on indefinite hold because of an issue within Rawspeed?
It is what it is. As mentioned, I personally don’t have any plans to keep working on this.

I believe there is an effort to rewrite rawspeed using Rust language.

I invoke the External Editor LUA script to open the raw file into PR4, and set PR4 to export the DNG back to DT. I edit the DNG and after export to JPEG and then copy the DT settings back to the raw file for archiving. I can then delete that DNG to save space.
I could probably use the External Editor script in a similar way to send the full sized DNG to Adobe DNG Converter to reduce the file size. I would still delete the full sized DNG but keep the compressed file since it’s a fraction of the size
It’s a couple of extra steps, but not too much of a burden once you’re used to it.
Note that you’d have to go into the External Editor script and add the raw file extension for your camera in order for the script to recognize the file. It was pretty easy to do, and my coding skills are practically nonexistent
I just noticed that there was a post by Andy Astbury with regard to issues with darktable being unable to open “high fidelity” compressed images processed in DxO 6.
Knowing that these images will open into Raw Digger and FRV, is there any reason why they would not open into darktable, assuming that darktable also has the ability to open files which can handled by the Libraw database.
From the LibRaw release notes:
- DNG 1.7 (including JPEG-XL compression) support via Adobe DNG SDK 1.7.x integration
RawDigger and FRV are commercial products and they decided to go through the trouble of integrating Adobe DNG SDK with them as they can charge for that. Most open source projects don’t enable this in LibRaw AFAIK, for mainly two reasons: the licensing terms are not clear at the moment, and integration itself is a PITA (e.g. no OOTB build scripts for Linux for starters).

Did you read the few posts above your post?
Yes, but the latest post from @kmilos helps me to understand the situation better.
Too bad, since the latest version of DxO is not only better than the previous version, but adds the ability to create much smaller DNG’s without any significant loss of detail.
I’ve been playing with the PR6 version for about a week now and I haven’t found much difference in denoise performance than with PR4, even at the pixel peeping level.
It’s unfortunate that the the compressed DNG aren’t compatible with DT, but you can reduce them using the Adobe DNG creator (you need to select version 14.0).
It’s a bit of a PITA, but it works.
@Dave22152 It appears that when the DNG convert is completed that the darktable edits are lost.
The DNG convertor shouldn’t do anything to your XMP files. It would create a new, compressed file that you can copy into.
If I wanted to use DxO and then have compressed files, I would generate the full size denoised DNG with PR, then run that file through Adobe DNG to create a new and additional compressed DNG. I would then perform my DT edits on the compressed file and delete the full sized DNG. That’s might be too much for some people, but if you want compressed files then that’s how I would go about it.

Good idea, but that method didn’t work for my file. DT wouldn’t read the Adobe compressed version.
You have to secure that the Camera Raw compatibility setting in Adobe DNG Convertor is 14 or less.
You need to go into preferences and change compatibility to “Adobe Camera Raw 14.0 or later”

So, a typical Z9 raw file is 60.3MB
That will render out of DXO PR6 at 190.4MB uncompressed, or 42.3MB in HFCompression
If you run the 190.4MB file through Adobe DNG Converter, the file drops to 175.2MB and WILL open in darktable.
The HF Compressed 42.3MB file becomes 27MB after running through Adobe DNG Converter and will NOT open in darktable.
And that is with compatibility set to Camera Raw 16.0 or later.
Did you try it with compatibility set to Camera Raw 14.0? That setting has worked fine for me, although I haven’t attempted to convert the new PR6 compressed format.
Update: I just ran a PR6 compressed file through Adobe DNG converter with compatibility set to CR 14.0 and it opens in DT without problem
