I’ve read through the common reasons for certain raw files showing up as skulls and won’t open. I’ve tried the suggested fixes/remedies. Nothing seems to work. The files in question were originally Pentax raw (pef) then converted to dng. I no longer have the pef version of these files. I have several, as in 100’s of dng files with this issue. Using Windows 10 and latest version of DT.
The other issue is that some of the dng files that display a thumbnail and can open, show white or black square block patterns as if some of the file information is missing. Are these corrupted in some way? I have no issues opening any of the dng files in RawTherapee or other programs.
Can anyone offer suggestions or a solution. Perhaps this will be addressed in the next version?
I had a similar issue with some of my DNG files. I noted that some DNGs were fine, while others showed skulls. The Skull DNGs were all ones created by Lightroom. I opened them in PS and re-saved them (might have adjusted some save parameters, cannot remember) and then they worked fine. Perhaps there was some encoding method used that Adobe can read which dt cannot…
Not sure if this helps, but seemed similar to your issue.
I’m not sure what you mean. Let me explain further just in case there was some confusion:
THe DNG files I saw that had skulls were all generated by lightroom, specifically it’s built-in HDR or Panorama outputs. To alleviate the skulls in darktable I used windows explorer, navigated to the file in question, opened it in Photoshop, and resaved (possible changing setting in the save dialog, I cannot recall). So no exporting was involved.
I cannot recall, but I may have removed the files from darktable and then re-imported them, but I cannot recall for certain.
I haven’t used PS or LR in a long time but PSE is definitely a neutered version and likely less feature rich or updated than LR. Based on what @BzKevin said, it sounds like it might be an Adobe issue.
