Support For DNG Files
I'm still learning about CO. A while back I converted many of my Nikon raw files to Adobe DNG. If I now switch to Capture One from Lightroom can these files be imported and allow me to make adjustments? This may be a very elementary question but I appreciate your help. Thanks.

All I can say is make a copy and try it.
I remember in the past having issues with C1 and DNG's. I just can't remember if it was C1's version of a DNG or Adobe's.
They may have resolved it. I just quit bothering with DNG as it's not really all that great for my work.
I use C1 and LR side by side. Different tools for different jobs.0 -
Converted DNGs should work in CO8. Best to try, you have 30 days. Note that the original NEFs gives probably a better image quality on conversion. Also, some tools do not work on converted DNGs like the Lens Correction tool. 0 -

Errrr...
Why should that be, Paul? Lossless DNGs are pixel-for-pixel identical to their source Raw files, as far as their image information is concerned.0 -
Keith Reeder there is a lot more going on in DMG then you thought. Check this article for example.
http://petapixel.com/2015/07/16/why-i-s ... le-format/
So basically DNG stripps some info out it. And some profile info is no longer recognised by processing software such as D-Lighting for example0 -
Andriy, I know a great deal about DNG - more than the author of that uninformed article, for sure.
Did you read the many comments completely rebutting its nonsense? You really need to, if you believe what the article has to say. And keep clicking on "load more comments", because there are hundreds, nearly all of them tearing the article to pieces.
What is "stripped out" of a lossless DNG is irrelevant to the image quality of the rendered image. If there are problems with how Capture One renders a DNG (in my opinion there are not), they're down to Capture One, not the DNG.
Specifically, this from the article is just plain wrong:but Adobe has changed that data to something that works best with ACR (or its Lightroom interface). Adobe created an open format in DNG but it built that open format on its own standards, specifically “Adobe Standard.â€
And D-Lighting? Of course proprietary metadata like D-Lighting is dropped - it's useless to anything but Nikon's software, and ignored by Capture One, Lightroom, Photo Ninja, and any other "third party" converter, so why put it into a DNG? But the image data - the read-out from each and every pixel on the sensor - is identical whether in a (lossless) DNG or a manufacturer's Raw file.
This is all basic stuff, Andriy. It's this lack of fundamental, easily-researched facts about DNG which gives rise to nonsense like that article, and which causes discussions like this to turn into unhelpful works of fiction, when such debunked articles are cited as "proof" that DNG is a problem.
Luckily, some of us know about DNG.
In fact, here's an interesting test you might like to try: from Capture One, export a Raw as a DNG. Now bring it back into Capture One, treat it like any other Raw, and develop/export it.
No image quality shortfall. None.
If you then do the same with a a DNG generated by Adobe software, you'll get a somewhat different initial result in Capture One, and it may take a little more/different work to get to a finished image: not because DNG is bad, but purely because Capture One creates a non-standard DNG conversion.
Which proves nothing about DNG except that Phase One has a "proprietary" approach to creating DNGs, presumably to make converting them into image formats in Capture One more like dealing with any other Raw. I actually believe that Capture One DNGs contain some embedded colour/tone curve info which Capture One then uses when the files are subsequently opened in Capture One.
And I think this because of what I see if I now take the same Capture One- and Adobe-generated DNGs, and convert/export them in an "independent" converter like Photo Ninja.
They are, to all intents and purposes, identical to one another - and to the exported original Raw.
Just for clarity, I've just re-performed this exact test, and the result is clear: DNG does not compromise image quality.0 -
Keith Reeder sorry for touching back your personal stuff, but the think is that DNG does not preserve some data from RAW file specific to Nikon cameras such as D-Lighting info and Curves, so when migrating from LR it becomes a pain. No argument that it preserves RAW data. I've added article to demostrate that. The DNG does not compromise quality of image however it strips some info from it.

Hi John,
I would download a copy of CO and test it. I tried using CO with my Nikon dng files (converted in LR) and had many issues. The trouble is CO treats these dng files as a "generic" dng file, it doesn't apply the tone/colour profiles specific to your camera. Basically a NEF and an Adobe DNG (created from that original NEF in LR) will look different to each other in CO. I find the colours are twisted way off in the dng and I can't fix them.
I haven't used dng for a few years now as I have only ever had issues with raw convertors that don't support it properly. I exported all my dng files to full size jpg's in the end just so I could use them in CO.0
