DNG output woes
I took some family Christmas pics with my Leica Q. The Q uses DNG as its native raw format. I imported the images into Capture One, applied keywords, then attempted to export DNG files to share with my wife who does NOT use Capture One.
There were several issues with the exported DNG images. The ONLY changes I made to the images before export was to image metadata. The exported DNG files had what appeared to be exposure changes -- they looked like they were brightened by several stops. Also, the exported DNG files were much larger than the original DNG files. Adding a half a dozen keywords should not have made that much of a difference. I was hoping for much smaller files with Capture One producing compressed DNG vs the uncompressed versions I get from the camera.
What I found that works is to sync my metadata changes to create XMP sidecar files then gave my wife the original DNG files plus the sidecar files.
My question is has anyone else exported a variant in DNG format and noticed messed up exposures?

Messed up exposures compared to what?
The original image as viewed on the camera's screen?0 -
So you have native DNG files from you Leica Q, you import them into Capture One, add metadata, and export them as DNG again. Metadata is saved in an XMP files, which probably means you have set your metadata sync settings to Full Sync.
As far as I know, Capture One does not store adjustments in the exported DNG.
If it is for the metadata you like to give to your wife, I suggest a different workflow. Just add metadata and then go to Export Images > Originals if you like to give selected images with metadata to your wife.
If you like to give the entire folder, that is all images, skip the export step and hand over the image folder which now has XMP files with metadata, to your wife.0 -

I do NOT have metadata sync to full so metadata is NOT written to XMP files. I was hoping that the updated metadata would be written to the exported DNG file. Since the exported DNG had messed up exposure (several stops lighter than the preview image displayed by Capture One) I actually didn't bother checking to see if the metadata was written to the file.
Yes, the solution is to update metadata, sync the image, then give both the original image plus the XMP file to my wife.Paul_Steunebrink wrote:

I understand that. Even if adjustments were added to the DNG I wouldn't expect anything other than Capture One to understand them.Paul_Steunebrink wrote:

That creates a Session like structure which is only of use if she, too, used Capture One. She doesn't.Paul_Steunebrink wrote:

Agreed,. This is the best solution.
But still, my question is this: If you import a DNG, make no changes, then turn around and export the image as a DNG wouldn't you expect the exported image to look the same as the imported image? It didn't. I think that is wrong.0 -
