DNG Previews from Leica M10r

The file of the dog on the couch shows just fine with a preview in my import screen. I would guess @GoldingD is correct that you should attempt to import through the files area instead of devices to see if that makes a difference. Also, it is best to always import through a card reader instead of using a cable from a camera.

P.S. I notice that you are selecting your source under Devices.

This can be an issue, try it under Files instead.

note, in MACOS, a SD drive shows up in both devices and files, in Windows, a SD card only shows up under device if the card is in the camera, connected to the computer via USB or even worse.

Some have had problems in MACOS if importing from devices.

For a similar posting , see (ref 1). Solutuion was fixing MACOS Files and Folders security. Also, see (ref 2)

note: Source of (ref 2) used to be more specific as to Lightroom Classic, looking back at older posting, it appears nektony has changed the contents of the document linked. Does anyone have a better document?

Ahh, and (ref 3) speaks to the very problem.

Moving on from above as of 15 AUG 2021, 4:45 PM (Southern California)

Mac OS Big Sur 11.4

Lightroom Classic 10.3

Camera: Leica M10r, is supported in Adobe Camera RAW

Native RAW is a DNG file

In Import, "Preview Unavailable for this File" displayed in grid view thumbnails

What Apple computer do you have?

I tried some sample Leica M10r 'DNG' images off the web and was able to see them in the preview window. I did make a change in Lightroom Preferences last night changing the pref's from 'dng' to 'DNG' I'll check wether this is what made the difference.

Sorry Guysk, first post here forgot the critical info.

Mac OS Big Sur 11.4

Lightroom Classic 10.3

Windows 10 Home Premium, LrC 10.3. Downloaded sample from the web, imported and preview displayed with no problem.

I just downl;oaded a few from https://www.dpreview.com/samples/6467167618/leica-m10-d-sample-gallery and from https://www.photographyblog.com/reviews/leica_m10_r_review#sample_images and they all preview in import just fine on my installation (LrC 10.3 on Mac OS X Big Sur)

So, common info to include when posting

• Adobe program name and version? Lightroom Classic version ??
• Operating System name and version? MACOS ? v?

hmm, I will need to get off my rear end, turn on a computer, download a sample, and take a look.

Suspicion is the DNG format specification used in the Leica DNG is not the full Adobe spec for DNG, and Adobe Camera RAW (including Camera RAW within LrC code) does not accept it.

Looking at (ref 1) , the DNG created by the Leica M10r, is supported, but requires LrC v9.3 or newer.

The DNG that Leica is creating probably does to use the full Adobe DNG specifications. And Adobe needed to treat it as if it was a camera specific RAW file.
