P: noise reduction for lightroom classic as a preset during importation

@Rikk Flohr: Photography 
this fact (the original RAW is embedded within DNG) has some unintended consequences in other software. for example trying to stitch a panorama using the NR-dng files, it instead used the embedded RAW without denoise. had to create tiff files for it to work.

ahh good to know. now it makes sense why the denoise DNG files are twice the size of the original RAW

@11329383  The mosaiced original is already included in the Denoise DNG to future proof against better models coming at a later release. 

they could also add a checkbox "Embed Original Raw File" whenever enhance/AI denoise is used to create the DNG (as it already exists for dng creation upon import in settings)

already we can create "ISO Adaptive presets". but unfortunately only using the legacy luminance/color noise reduction. there should be some kind of implementation of AI denoise in its place!

I really would not recommend that. I would reserve Denoise for the relatively few files that actually benefit from it.

The problem is that the denoised files are demosaiced (encoded into three channels instead of the original one) - and there is no way to go back. Once denoised it stays denoised! It's irreversible.

In other words, you should consider denoised files as derivative files that you can recreate. You should not delete the original raws! So you will end up with a full set of duplicate files.

And aside from all that, totally eliminating all noise cannot be a goal. In most photographs shot under normal circumstances under reasonably good light conditions, noise is simply not a problem. On the contrary, eliminating it completely can result in an artificial plasticky look. Occasionally, under particularly difficult conditions, noise can be a problem - and then you have this extremely effective tool at your disposal to deal with it. But there's no reason to run it wholesale on everything.
