This is probably a rather odd question. If one turns off the Denoising and & Demosaicing control before editing, how does that affect the image in regards to Demosaicing is concerned? Certainly, noise reduction isn’t applied but don’t all raw files require demosaicing? Also, is Demosaicing the same for every option, Standard, Prime, DeepPrime 3, and DeepPrime XD/XD2s?
Without demosaïcing, you can’t edit RAW files and can’t be turned off. Denoising is optional but is always worth it, even for low ISO files.
Exactly what I thought. However is demosaicing affected by which level of denoising and demosaicing is selected?

The demosaicing engine differs according to denoising;
HQ - PRIME (recommanded) - DeepPRIME (all options).
With PhotoLab, there’s no need to disable denoising, so you can minimize its effect.

What do you mean by “Demosaicing control”?
AFAIK, no such thing in PL.
I have hundreds of guesses what you had in mind. Please limit my choices to expect any possibly relevant answers.
What is your problem?
There’re 2 denoising moments: before the demosaicing on the raw data or after the demosaicing on the rgb data.
In general the demosaicing is looking for pixels that are very different from their surrounding pixels. Mostly denoising is done on the rgb data. But PL has also algorithms that are done on the raw data.
Demosaicing controles as such I’m not aware of except if you mean something as color temperature. That effects the way demosaicing is done.

With me it’s called “DxO Denoising Technologies”. PL8,win10.

Swmurray, I received your response via email. Not sure why it didn’t show up here. I understand every raw files requires Demosaicing. My question is simply what happens when you turn the control off? Could it just be a matter of the control being mislabeled? Please see the image I attached above.
Yes, you can switch something on and off. I assume that denoising can be switched on and off, but demosaicing can’t, as that would certainly look very surreal 
I don’t know if it is mislabeled or just a different interpretation. DxO applies the Prime and other denoising algorithms in combination with demosaicing, and a user can turn “ON” D&D and use the Standard denoising algorithm for tiff and jpg files without any demosaicing. So perhaps they see these options within the "Denoising and Demosaicing group as different demosaicing algorithms too, not just different denoising algorithms.
I withdrew my earlier comments about the “standard” algorithm as incorrect.
Applying the same slider settings with the standard algorithm to a RAW file and a tiff exported with “No Corrections” does show some slight differences when compared, but I cannot tell if this mean the demosaicing/denoising algorithms are different for the RAW versus tiff when applied separately.
What are you using? I don’t have what you showed before.

I am using PL8 on a MacBook M3 Pro. MacOs 15.4.1
Depending on what exact version you are using, there has been a change:
PL8.3…
PL8.5…
I would agree that the new title is somewhat misleading as demosaïcing is either off for non-RAW files or automatic for RAW files. IMO, there is no need to mention it on the title, unless it was just to fill the space where “Technologies” would have been removed

In my install it is also called “Denoising and Demosaicing”.
I think it is in the sens that the engine you choose below is determining how both tasks are performed, because with DXO both demosaicing and denoising as done at the same time, they are intertwined.
There is no option for demosaicing per se, the slides affect denoising. But the choice of the algorithm (HQ, PRIME, etc) affects both,.
Thanks for everyone’s response. Can I assume then, that the Demosaicing process changes or is adjusted with each level of noise control? For example, DeepPrime 3’ includes a level of Demosaicing that differs from the Demosaicing tailored for Prime?
I don’t think the process itself changes. Before that process the source, raw data, is changed/corrected. And the amount of correction differs between the 3 denoising routines on RAW. High quality is done on the RGB.

Just a question that might have been covered before. I have DxO PL Elite 8.6.4. Is there a difference in IQ on the sequence Denoise is applied? I currently edit, crop and then apply denoise and save as a Jpeg file. Or should I apply denoise then save a DNG or TIFF file and then edit the saved file? Thank you.
I don’t know what you mean with this. The main three denoising techniques are done on the raw data when exporting the image. What you see during editing is not the total denoising.
A jpg is a finished, compressed, image. Don’t use it when you want to edit it further. Use TIFF 16.
