Lightroom 9.2 ate my pixels

After the last update (Windows 10 64bit) some photos appeared to lose a significant amount of the pixel data, precropped to 16:9 ratio instead of the original 3:2. They can all be manipulated but cannot regain the lost pixels. As shown in the attached screen grab, affected and un affected images are in the same format, and same camera (CR2 files from Canon 5D mark 3). Both of these images were reset again to lightroom 9.2 defaults as first attempt to correct the issue, which didn't help. This problem persists in ACR12.2 as well, when opening from photoshop.

Re: Lightroom 9.2 ate my pixels

You probably have your 5DMk3 set to shoot in 16:9 mode.  You could try this plugin to recover the cropped pixels

Re: Lightroom 9.2 ate my pixels

Hello Bob, 

Thanks for the detailed explanation, but this is definitely not the case. As Ive mentioned, some of the images from the same shoot appear as such, and others don't. This bug occoured only after upgrading to 9.2. 

 

CaptureOne also seem to have no problem with opening the file with the correct aspect ratio.

Images from the same session with the camera set to 3:2 aspect ratio will in fact be 16:9 if shot when the camera is in video mode. I suggest trying the Adobe DNG Recover Edge plug-in at the link Bob_Somrak provided. If that fixes the issue you have a solution. If not I suggest uploading one of the 16:9 CR2 files to Dropbox or other files sharing site so we can examine it.

Re: Lightroom 9.2 ate my pixels

Hey Todd, As you both suggested I've tried converting the file using the edge recovery through the two different ways lightroom can convert RAW to DNG.  This process failed to restore the pixels. 

 

As mentioned before CaptureOne didn't face any issue in opening the original, and exported DNG from CaptureOne works correctly on Lightroom. I would like to stress again that this problem appeared only since the last updates, as these photos were imported long ago. 

 

Here is the original RAW:

and that's the converted DNG from CaptureOne 20:

"Hey Todd, As you both suggested I've tried converting the file using the edge recovery through the two different ways lightroom can convert RAW to DNG. This process failed to restore the pixels. "

 

After applying the DNG Recover Edges plugin to the DNG file you need to reset the Crop tool as shown below. Does that work for you?

Re: Lightroom 9.2 ate my pixels

Yes now it does. I had to import to lightroom the resulted DNG I have exported for you . 

 

Although it (Convert>expoert>import) solves the problem, I'd say that since this issue doesn't appear in other programs and previous versions, I'd still consider it as an adobe specific issue.

Re: Lightroom 9.2 ate my pixels

Adobe fixed this issue for newer cameras.  They COULD fix this issue for the 5dMk3 but they have purposely chosen not to.  The logic is the 5DMk3 was released before the fix was implemented and it would affect already imported photos.  I feel this was a poor excuse on Adobes part but at least Recover Edges fixes the problem.
