Question

Photo edits after Denoise converts it to .DNG - should I edit the DNG or go back to RAW?

I know DNG files are basically RAW files, but I'm kind of obsessed with making all my editis in the original RAW.

So when Denoise converts to DNG and I want to make more adjustments, is there any reason I shouldn't just make the adjustments on the DNG? Or is it better to go back to the RAW and start over?

Thanks!

It would be completely useless to start over, because the denoised DNG is created from the unedited raw file. So if you edit the raw file and then create a new denoised DNG, then you'll get the exact same DNG as you got the first time. Edits will be copied over to the new DNG, so the end result is also exactly the same as when you make those edits directly on the denoised DNG.

Not sure what you mean, but I'm saying if after I create the denoised dng, I decide I want to make changes to exposure or tweak some of the colors, would it be better to go back and do that in the original raw file, then denoise it again? Or just do it in the dng that I already denoised?

Easy enough to try and see for yourself. I have a feeling the answer may be dependent on the content of your image and what edits you make.

Denoise outputs a demosaiced RGB linear DNG. It's no longer a "true" raw file.

The denoised file can be recreated at any time, but the opposite is not possible. This is a one way street, you cannot go back. The denoised file is a derivative file. Always keep the original to go back to.

When you run Denoise, all adjustments are temporarily suspended, and the process is run on the original raw file. Then the adjustments are re-applied (but may look slightly different).

Armed with that knowledge, you should make your own decision about workflow. I don't think there is a definitive answer. Personally, I use it very sparingly. I just don't think it's needed very often.

IMO given that you have used Denoise, and once you've satisfied yourself through trials that you could not have achieved (more or less) equal results without that step - I'd say, simply edit away as if this was a normal Raw.

There would be no purpose in making a Denoise version, if you did not feel you could then adjust it!

I would say the same things about an HDR merge too. The outcome from both are designed to remain very conducive to ongoing adjustment within LrC.
