Extracting NEF from DNG

[dkabat]

Prior to reading your book I was imbedding the NEF in the DNG.  I can see the preferred method is your suggestion.  Have found where I can get rid of embedded by reconverting the DNG without the embed option.  Item of curiosity, if I were to extract the NEF from the DNG could I get a sidecar XMP file with the raw adjustments included in it?

Dan,
I don't know how you would get the data out and into a sidecar (this is one of the many awkward workflow issues with embedded DNG files). Of course you could manually recreate the information, but that does not seem to be what you are looking for.  This may be possible in the future, but I don't think it is now.

If you want to convert your DNG files with embedded previews into DNG files without embedded previews, you simply reconvert without the Embedded option checked.

Thanks for your time and all of the excellent information

You're welcome.

In Bridge, select the DNG file and examine its File Info. From the menu at the top right, save the metadata template. Then apply this metadata to the NEF file. This copies IPTC data, and creates an XMP file for the NEF. But Apply/Replace Metadata doesn't include your raw adjustments, so....

Select both images in Bridge, launch Camera Raw, select both and Synchronize. It's pretty manual but easy enough.

ps I think it may be possible by hacking the metadata templates and the NEF file's XMP. Open the metadata template in a text editor, copy the crs section and paste it into the NEF file's XMP. However - a big however - when I tested this with Bridge 1.0.3 in Windows, Bridge correctly showed the NEF with the DNG file's raw settings (I'd knocked down the Saturation) but displayed an error message that seems to cycle through all the XMP file's properties until I stopped the Bridge process.

If Adobe would let you export an XMP document from the DNG, then you would have everything in one spot, without the manual work-around.  At this point, I don't think it's possible. (It might work, if you opened the DNG back up in CS1 and made a small change to the metadata, since CS1 does not rewrite DNG files, but rather, creates and applies XMP sidecar files).
