p.1 #1DxO PureRAW - keep a copy of your original RAW file
Should I delete my original image after processing it with DxO PureRAW?
This information applies to all versions
This depends entirely on you, and on what you intend to do with your images. Keep in mind that a RAW file is THE original, and cannot be replaced.
On one hand, DNGs created by DxO PureRAW can be considered 'perfect' files, and if you are sure that you won't ever want to reprocess them, you could delete your RAWs.
On the other hand, many users have been so impressed with the high-quality results delivered by DxO DeepPRIME that they decided to reprocess their archived RAWs, many of which were taken over a decade ago.
The best idea may be to keep the original RAWs in case we eventually offer even greater improvements to our RAW processing. DxO PureRAW is going to evolve over time, and so are its denoising capabilities....Show more →

That's not specific to DXO. You should always keep RAW files in native format if having the original is important. Nobody knows what future software will bring and to what degree the same processing can be applied to any kind of DNG as the original RAW file. Obviously for (commercial) work that is completely finished it may not be worthwhile.

The answer "it depends..." indeed.
It depends on where the subsequent processing would take place and whether the processing software/app (Lightroom, PS, Capture One, etc) works well with the DNGs from DxO PureRAW, or if processing from the genuine raw files somehow works better. For example, in my experience, I find that processing DNG files (generated by DxO) in Capture One works well, possibly even better than processing from the corresponding raw files.

I keep my SOOC raws. That's just my choice. I reprocess old photos from time to time, sometimes to measure the improvements to modern software, sometimes to measure how my skill has improved (or not improved).
I've never had to use a RAW to establish provenance. That's probably a good thing, because if I ever have to do that, it likely will be an unpleasant way to spend my time.

Aside from true “missed” (grossly out of focus, terribly bad exposure, accidental shutter button presses while aiming at my left foot) I keep essentially all of my raw files.
