What would be data that is contained in such a DNG? Exported from Capture One, I mean?
Wouldn’t that be same as TIFF?
Also, as a side note. I have tried for example to apply Lightroom Noise Reduction AI and than open that DNG in PhotoLab. DXO sees it as just a regular noisy RAW file in DNG format, and as far as I noticed it works like original RAW file, but it does not recognize the noise reduction made by Adobe. I do not know if this is because Adobe does not save it in a way others can read it, or does DXO need to do something to read it. But I would imagine that different proprietary technology would not be available for further adjustments, effectively losing any advantage of doing so.
PhotoLab does record linear DNG, but lot of the info is backed in, stuff that only works in DXO , while the standard data about dynamic range and color etc is open for other apps to work with. It makes sense for that workflow because DXO is not strong in database mangament etc as are other apps. Plus its for users to already use Lightroom or Capture one and want to continue to use it, but also want the best image quality and best corrected lens problems that DXO offers.
If by opening up RAW, you mean RAW that is converted to DNG and opening it up in DXO. I am curious what would be the advantage of that over say TIFF? Because DXO if I’m not mistaken calibrates their lens sharpness and optical corrections manually, and if that is not done by DXO, where would that correction information come from? This would only leave DeepPrime de noising and demosicing technology and with that I can agree it would be useful to use it in a non supported RAW files , saved or converted to DNG, with for example DNG converter from Adobe. Interestingly, though when Adobe released their latest Noise Reduction AI , it too does not support DNG, or TIFF or JPEG, but only original RAW files. I don’t know what is the significance of that.
