I hit the wrong key
the LR version is 12.2.1
However, if I process the file and save in TIFF format. It does work fine. LR can read the tiff file. LR was able to read the DNG in the preview release.
My M10Monochrome DNG, the DNG file generated by using a leica M10Monochrome camera - the photo ai process the file and it is unreadable in DNG format and yet you can read the file in tiff format.
anyway, what do you mean by raise a support request at the main website?
OK understand, if you use Photo AI as a standalone or send the original DNG to process the file will may overwritten as DNG is a output format for Photo AI and I don’t know if Photo AI will identify it as a RAW image.
I checked on LibRAW and RAW from the Leica M10 Monochrom is supported so the best option is to raise a support request at the main website as they will be able to identify why the DNG cannot be opened after being updated.
