I replied on @OXiDant saying that the DNG with raw file where even smaller as the original raw file. Using the Adobe DNG converter and the same embedded jpg size results in the same size as the original raw file. I also mentioned that you still need a raw converter that can convert that specific camera.
With the demosaiced raw file it has the same size as a regular TIFF. But with no gamma correction.
So I’m still wondering what is the purpose of this DNG?

@George i remark about two DNG’s which was: first we got a DNG with a AdobeRGB colorspace which also could contain your corrections as masking and local corrections. And in the beginning it wasn’t even possible to re digest again in dxoplv5? So it was to use as tiff in a dng container for other programs like adobe’s photoshop.
The later version of dxopl was it possible to store custom DNG as a negative and re digest/feed in dxopl.
After the new workingspace which holds now legacy (AdobeRGB) and Wide colorspace they created a new kind of DNG.
The rawdng, which as i remember correctly have the same output as there other converter Pureraw does. So no local corrections.
It holds the wide colorspace, denoised in (deep) prime (XD) and with a set WB. (which is logic because denoising means also converting to RGB pixels) that’s v6 v7 timestamp right?
That’s what i remember i could be mistaken.
I need to start me application to check if it’s what i am writing
But still demosaiced. I wouldn’t call it a rawdng.

I think dxo (staff) did calling that new version dng rawdng in the first test’s.
Din’t know which name it is now in de export window, i didn’t use it because the file size is huge.
Fore people who is editing a lot of images in batch form then it could be time saving to convert first to DNG and then multi selection editting.
(also to get the iptc exif data inside the file instead of a xmp file sidecar.)
