robsonj Posted January 18, 2018 Share #1 Posted January 18, 2018 Advertisement (gone after registration) Hi there, I don’t think this is an issue with my Leica M, but given its new to me, I thought I would post incase anyone has seen such an issue that did turn out to be camera related... On importing images to Lightroom from the sd card (compressed dng) I’ll see a couple of corrupt images (previews - from embedded preview image) in the library module. If I flip to the developer module, the raw file is perfectly fine. If I regenerate the preview, the corruption goes away. One would think it points to the camera saving a corrupt preview images with the dng, which is resolved on a preview regeneration in Lightroom. The weird thing is if I do the same import to another computer... no corrupt previews. So that would point to an issue with the computer, but I only see this from the Leica shot images. 2 imports of a couple of hundred images each time usually results in 1- 2 corrupted images as described above. One thing worth noting is that I’m pretty sure the corrupt images where shot in continuous mode and shot at the point of a full buffer. Very weird and easily remedied by generating the previews. Any thoughts appreciated. Cheers Jonathan Link to post Share on other sites More sharing options...

Exodies Posted January 18, 2018 Share #2 Posted January 18, 2018 There is a problem with Lightroom and the image names generated by Leica. It causes LR to identify the wrong preview under conditions which the forum cannot agree on. As you have discovered, it’s a cosmetic problem easily overcome.

robsonj Posted January 18, 2018 Author Share #3 Posted January 18, 2018 O wow, I would never have thought of that, glad I asked now! Thankyou Link to post Share on other sites More sharing options...
robsonj Posted January 19, 2018 Author Share #4 Posted January 19, 2018 Ok, so this happened to me again today. The image was ok in the library preview, but corrupt in the develop module, regenerating the preview image resulted in it then to being corrupt. So I installed Affinity Photo to see if it could read the same file... it could, without issue. I then tried via CameraRaw, it also had no issues. I uninstalled and reinstalled Lightroom, it was then ok with the file. At the minute I don't think this is a camera issue. Link to post Share on other sites More sharing options...
Exodies Posted January 19, 2018 Share #5 Posted January 19, 2018 Could you be more specific about “corrupt”. The problem I referred to is that it shows the preview of a different photograph. Link to post Share on other sites More sharing options...
robsonj Posted January 19, 2018 Author Share #6 Posted January 19, 2018 Yea, this was different then. The image looked corrupt, all sorts of random blight coloured garbage across most of the image etc Link to post Share on other sites More sharing options...
Exodies Posted January 19, 2018 Share #7 Posted January 19, 2018 Advertisement (gone after registration) If you have tried different cards and different methods of formatting them I would send the camera to Leica with screen shots of the corrupt preview .

robsonj Posted January 19, 2018 Author Share #8 Posted January 19, 2018 Yep. As mentioned above. After reinstalling Adobe Lightroom the image was uncorrupted, so I think it was a Lightroom issue. Very odd though as it only affected 1/100 images, I had also set the camera to save dng+jog. The jpg was never corrupted Link to post Share on other sites More sharing options...
Herr Barnack Posted January 19, 2018 Share #9 Posted January 19, 2018 (edited) I had trouble with corrupt images in the past. I quit photographing politicians and haven't had a bit of trouble since. Edited January 19, 2018 by Herr Barnack 3 Link to post Share on other sites More sharing options...
dugby Posted January 20, 2018 Share #10 Posted January 20, 2018 On importing images to Lightroom from the sd card (compressed dng) I’ll see a couple of corrupt images (previews - from embedded preview image) in the library module. Hi Jonathan. Will the same issue occur if you copy the files from the SD card onto the computer, and then us LR to access the files on the computer's hard disk ?

ocho Posted February 6, 2018 Share #11 Posted February 6, 2018 This being the only similar topic I can find I thought I would try here and see if anyone has the same problem with Lightroom import as me! I shoot my M240 in DNG only but on import to Lightroom it's rendering a small percentage of the frames skewed. Auto correct does not..... I have to crop and straighten, losing some of the frame. This has only just begun to happen and is very confusing as at first I thought it might also be a corrupt card. Anyone have anything that may help me here?

Exodies Posted February 6, 2018 Share #12 Posted February 6, 2018 Is the picture skewed when you use “play” on the camera? 1 Link to post Share on other sites More sharing options...
ocho Posted February 7, 2018 Share #13 Posted February 7, 2018 No, it seems fine. I have discovered that if I use the "update" button in the Transform section of Lightroom then the pictures corrects however I can't understand why this might be?

Exodies Posted February 7, 2018 Share #14 Posted February 7, 2018 The last person with a similar problem reinstalled Lightroom to get rid of it. It’s very strange. Link to post Share on other sites More sharing options...
robsonj Posted February 7, 2018 Author Share #15 Posted February 7, 2018 That was me, and it worked for a while, then the issue came back (maybe 3 images out of a 1000). However, I found if I just copied the images off of the card using the OS X finder, they were fine, so in my case it’s definatetly not the camera, it’s lightroom. And wonky images are for sure down to my wonky eyes Link to post Share on other sites More sharing options...
