If you open one of those DNG files in Photoshop/Camera Raw or Lightroom, is the lens profile information where it should be?
Is the lens profile information what is damaged for C1 so converting them the DNG won’t help?
Or if you convert an NEF that C1 reads fine, to DNG, does C1 still not have lens information, which means the DNG converter isn’t packaging it in a way C1 can read or removing it, entirely?
What camera model are these from where a lens profile rather than just lens model information is stored in the NEFs?
If I import a .nef file into Capture One that can be read it shows the lens profile.
If I then convert the same file to .dng and import into Capture One the lens profile is missing.
The same image file (as a .nef) shows the lens profile in both Photoshop and Lightroom.
I've just imported the converted .dng files into Lightroom and it shows the lens profile.
So Lightroom can read both the original .nef and the converted .dng files and show the lens data for both but Capture One can only read the lens data for the .nef files... interesting...
Ok, your second sentence is what I was asking.
What camera model?
For DSLRs, PS/ACR and LR use external profiles, so are not actually reading lens profile information from within the raw file, and instead or just reading the lens model information and matching up an external profile with the lens model.
For mirrorless cameras PS/ACR and LR there is a built-in profile (not sure if in the raw or in the software) that PS/ACR and LR applies automatically and this correction cannot be turned off.
I don’t know anything about how C1 works. Do you know if C1 has external profiles or does it only apply conversions that are actually specified in the raw files, which woudn’t be more DSLRs.
I guess what I’m asking is about your terminology. Is what C1 can’t see the lens profile information in mirrorless camera raws (if such information exists in reality, I don’t know) or is what C1 can’t see the lens model information that it would need to determine what lens profile to apply?
