Should a DNG look exactly the same as the parent RAW?
I don't use DNG file format, but figured I might want to convert a bunch of RAW files some day, so I downloaded the Adobe DNG converter to see what it was all about. I assumed that the DNG would look exactly like the RAW file it came from when viewed in Capture One, but they do not. Just checking to see if this is "normal" for working with a DNG.
I Converted an untouched RAW file from a Nikon D800e to DNG with the Adobe converter. When previewing them side by side in C1Pro:
The DNG has a dramatically different color balance (more red) even though the "numbers" in the color balance menu are set the same for both (Kelvin & tint)
The Nikon RAW file appears slightly sharper at 100% than the DNG. Sharpening numbers are identical in C1Pro.
----------------------
Thinking maybe I missed some adjustments somewhere, I copied ALL the adjustments from the RAW to the DNG and they still looked the same as before copying. DNG less sharp, more red.
I then tried exporting the RAW file from C1Pro to a DNG. The DNG from C1Pro looked almost identical to the Adobe DNG conversion (there were some very slight differences), thus more red and softer than the C1Pro view of the Original RAW file.
Just for fun I exported a DNG file from C1Pro out to a DNG file. It looked exactly the same in C1Pro as the "parent" DNG file as long as I exported the "Original". When I chose to export a variants the color balance went nuts. When I exported the original and selected to keep the changes with the export, all I got was the original unchanged DNG file, without any changes that were applied. I was unable to export to a DNG processed in C1Pro without losing the changes made in C1Pro. I am guessing there is a way, but I haven't figured it out yet.
So, my conclusion is, be prepared for some changes when exporting from RAW to DNG, albeit very minor and don't expect to be able to export a modified DNG from C1Pro as a DNG, and keep the modifications you made in C1Pro.
(As expected, exporting from a DNG to a TIF from C1Pro produced a TIF that appeared identical to the modified DNG)
----------------------
Does C1Pro handle DNG files in the same way as RAW files?
I read in several places on the web that changes to a DNG file are stored IN THE FILE itself rather than in a sidecar, but that is not the case with Capture One. It appears that they are stored in the Capture One database not within the DNG file. When I make changes to a DNG in C1Pro, the DNG file itself does not contain those changes when opened by another application. You must export it from C1Pro to retain the changes.
Can you revert a processed DNG file back to its original unchanged state after it has been exported from C1Pro? I could not figure out how to do that.

It was your question - The answer is No, because you have converted the RAW first time with Adobe DNG Converter. Adobe has DNG version 1.4 (I mean), C1 can only read version 1.2. The first time converted with Adobe DNG Converter, the next time with C1
DNG Converted File should look exactly the same as the parent RAW only if you are using a new Adobe Software like Adobe Camera RAW (Version 8+) or Adobe Lightroom (Version 5+)[quote="Geezerhood" wrote:

No and yes - Yes - If the Camera produced DNG File is this your RAW (like some Laica Cameras). No if this is a Adobe DNG converted File. This is no more your originally RAW file.0 -
Thanks for the reply. I think will stick to converting /exporting to DNG in Capture One when needed, as that seems to give me the closest conversion to what I am seeing in the original RAW file. 0 -
I have never figured out what the value of a DNG file is. Yes, Adobe does always seem to be first off the mark to support new camera RAW files, and at times one could be forced to do the double step conversion to DNG, using the latest Adobe converter, and then open the file in the software you really want to use.
However, contrary to what Scott Kelby recommends in his books, I don't see the value of building DNG conversion into your workflow. Always, Always keep your original RAW files!0 -
