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?
