P: Exporting DNG (from Merge) as a new DNG w/ Compatibility set to 14.0 creates a damaged file

Hello, I also work independently for the real estate agent and I also have this problem, I take a lot of HDR photos for work and the merge to DNG does not go well, the file is empty, I cannot open it and it is low in MBs, which is not normal for an HDR. I work with Bridge and I have already tried everything with Lightroom, Photoshop... but it goes wrong with camera RAW... I have already submitted several reports to Adobe but I have heard nothing! I have to use the latest version because the program doesn't see my photo files... I'm slowly getting desperate 😞   Sorry is in Dutch, see difference between old version and new version

I'm unable to reproduce the problem in my LR 13.3.1 / Mac 14.5 with a quick test, so there are likely conditions triggering it that we haven't identified. In situations like this where Adobe can't reliably reproduce the problem, they're unlikely to pay much attention unless many people report similar symptoms.

Do you have a sample original photo you could share here? If so, select it, do Metadata > Save Metadata To File, and upload the original photo, it's .xmp side car, and the exported problem DNG to Dropbox, Google Drive, or similar and post the sharing link here. That would be more likely to allow Adobe to reproduce the problem.

Thanks John.  Using LRC 13.3.1.  Mac OS is Sonoma 14.5.  (OS was recent update - wonder if that's causing fits for LRC export.)

Which version of LR are you running?  (Do Help > System Info.)

Spoke too soon.  Using Compatibility 15.3 or later works and creates ouptut .dng, but the pics are really dark and not at all what they look like in other apps, including in LRC.  So not happy and not understanding why the files stopped creating correctly when Comp was at 14.0 or later.  Frustrating and may lose this customer as result becuase only work with LRC.

Good morning.  Also a photographer for Airbnb - same export requirements (as .dng, compatability at 14.3 or later) and had the same issue for recent shoot 2 days ago.  I did 12 shoots in April, first part of May without incident - so this freaked me out.  Changed the Compatibility setting to 15.3 or later and export worked fine.

One other thing I noticed that wasn't mentioned in this thread is that the exported file when Compatibility was set to 14.3 or later did not show a preivew in Finder - bigger concern was that the files averaged around 183 MB in size - 10x to 12x larger than the .dng that was being exported!  

I confirmed the bug recipe no longer results in error in LR 13.3 / Photoshop 25.9 / Mac OS 14.4.1.

On the export dialogue set compatibility to "Camera Raw 15.3 or later" will solve the problem if using Lightroom Classic or Photoshop for editing. Alternative try running the failed exported DNG files through Adobe DNG convereter using the latest camera RAW setting available in the dialogue.

Hope this helps.

Regards

hey mate did you solve this I have Airbnb as a client and the merged HDRs dont save in DNG as a merged file.
