Re-import Monochrom DNG files to Lightroom

Leica Monochrom (M10) DNG files can be opened as original DNG in TopazAI and edited. But an error occurs when trying to re-import into Lightroom.
Steps to reproduce issue:

  1. Step 1. Send Leica M10 Monochrom DNG file to TopazAI using “Lightroom Plugin Extras > Process with TopazAI” & “Edit a Copy” (If one chooses “overwrite” the original file gets ruined)
  2. Step 2. Click “Save to Adobe Lightroom Classic” (with or without editing steps)
  3. Step 3. Lightroom says " “Lightroom has encountered problems reading this photo.” along with a “!” warning: “You will not be able to make adjustments to the photo.”

Topaz Photo AI [v1.5.2] on [Mac]; Lightroom Classic [v 12.5]

Thanks for reaching out. We currently have a known issue with monochrome RAW files in Topaz Photo AI.

I would recommend converting your Raw monochrome files to TIFF or JPG before sending it to Topaz Photo AI for processing.

You can do this easily with the Photo > Edit in > Topaz Photo AI method.

We will be working on fixes for these monochrome Raw files soon.
