Leica Q2 monochrome DNG file results corrupt after Topaz Photo AI processing

Whatever picture taken with my Leica Q2M and processed by Photo AI (v.1.3.7) via my MacBook Pro (M1 macOS Ventura 13.3.1) results corrupt and cannot be opened by Lightroom, LrC or Photoshop.

The result is the same after a stand-alone process via Photo AI, or via LrC plug-in

Other DNGs taken by other cameras (Leica CL, Leica SL2) don’t have any issue.

Is there some incompatibility with monochrome cameras?

Thanks, Marco

@marco.gamberini Thanks for reaching out.

The Leica Q2 monochrome IS technically supported although that doesn’t guarantee perfect results every time because RAW files are notoriously tricky to work with.

Can you upload the original file here so I can run some tests?
I want to deduce whether it’s a Photo AI, image, or hardware conflict.

Hi, thanks for the reply.
As the files are quite large, I’ve uploaded them into google drive, here’s the link:
Ciao, Marco

@marco.gamberini Thanks for uploading those images.

I was also unable to import the images into Lightroom after processing with Photo AI.
However, I did find a workaround.

If you import the photo first into Lightroom then use the Photo > Edit In > Topaz Photo AI workflow, it’ll process a TIF instead of a DNG and it’s able to export the image to Lightroom after processing.

Give that a try and see if it works for you.

Hi Tim,

yes, the workaround works, the tiff-transformed image can be processed by Photo AI and then moved back to LrC not corrupted.
As a temporary workaround could be fine, waiting for the final fix.
Any idea if there is a way to manage the size of the DNG or TIFF Photo AI processed files?
Usually an 85MB DNG file becomes a 280 MB monster after Photo AI processing, this not only for the B&W shots from Leica Q2M but also for the color ones from my SL2.
Waiting for your feedback, ciao.

I’m glad the TIF method works for now. Thanks for your patience as we get the RAW route fixed.

Unfortunately, there is currently no way to manage the size of the “monster” DNG. This is particularly common when Upscale is enabled. Decreasing the change in file size is also on our list of priorities.

Let me know if that answers your question.
