algrove Posted October 2, 2014 Share #23 Posted October 2, 2014 I have experienced the same issue and am starting to hear of a few other cases. Here is my thread which may help a bit: http://www.l-camera-forum.com/leica-forum/leica-m-type-240/345130-strange-image-output.html There was a lot of good suggestions by forum members. I have not solved my problem but it doesn't happen very often so I try not to worry. One thing I was able to find out was that if you exit out of LR and open the file in Photoshop (not sure about other software), the file will actually render properly. Another issue I recently noticed was that after import of images into LR, there would be some oddball picture in the middle of them all which was taken months prior. If you then open that picture in Photoshop, it will render as a completely different (and proper) image. Pretty strange behavior and I really don't think it is related to they SD card. Best of luck and let us know how it works out. Now this is getting all too familiar. I have had recent lockups and after importing into LR I find files from nearly a year ago hanging around between new images. And what's worse is that I am remembering my lockup occurred in the area of where the "old" image was sitting. Very strange behavior! Link to post Share on other sites More sharing options...
CheshireCat Posted October 3, 2014 Share #24 Posted October 3, 2014 Interesting. So did the OP camera lock up sometime when taking the pictures discussed here ? Link to post Share on other sites More sharing options...

wlaidlaw Posted October 3, 2014 Share #26 Posted October 3, 2014 Without analyzing one of the corrupt files, this is all useless speculation. Perhaps to put things in a more positive light, people are making suggestions of possible causes, which might give rise to ideas for solutions to try out. In that you can usually get round the problem by opening the image in another program (e.g. Photoshop), suggests to me that the issue is not in the image itself but in the way that either LR or C1 are handing the image.

PNCD Posted October 3, 2014 Author Share #28 Posted October 3, 2014 Lots of comments and advice, thank you. To try and recapitulate: The DNG files were copied from the SD card to three different locations, with different images showing up as 'damaged' without any processing - just copying The SD has been used before and was purchased from my local Leica dealer in Geneva I have tried to rebuild previews and metadata with no observable difference in the 'damaged' files in LR. I have used MediaPro and see that some files display as 'damaged' but not necessarily the same files. It seems to me that if the SD was corrupted then the files in all three locations would be the same: 'damaged' or not. There are differences between MediaPro and LR such that SOME 'damaged' files might display correctly in one or the other. The only known difference from this series versus previous series is the upgrade of Leica firmware: same SD card, same camera, different firmware. I will deal with what I have, but I will be extra careful to take a run of photos from now on. Thank you all. Link to post Share on other sites More sharing options...

If you then open that picture in Photoshop, it will render as a completely different (and proper) image. Pretty strange behavior and I really don't think it is related to they SD card. I have had similar things happen on my Mac at times - not a camera issue but some glitch in the copying process (it has happened when copying old files from drive to drive and from other cameras too). It seems to be assigning a different file name and preview jpeg to the actual image (sometimes I've lost the preview, reopen and re-save in Photoshop which solves the problem) and I'd be interested to hear an expert opinion on this behaviour myself. The problem I have is that I suspect that there are an awful lot of potential problems that I know nothing about and which I all too easily ascribe to something I don't really understand!

Guest JonathanP Posted October 3, 2014 Share #30 Posted October 3, 2014 Not wishing to distract from PNCDs issue, but: Another issue I recently noticed was that after import of images into LR, there would be some oddball picture in the middle of them all which was taken months prior.

I think are probably the image ID problems that Wilson mentioned above. This needs Leica to fix in camera firmware update. More details later in this thread: http://www.l-camera-forum.com/leica-forum/leica-m-type-240/275209-leica-m-240-image-unique-id.html To fix an image that has duplicate image ids you can use ExifTool (or even my 'green shadows' Lightroom plugin). The image data is fine but Lightroom and Bridge get their preview caches in a twist due to the duplicate IDs, however once opened in an editor you see the real underlying image data. But I don't think this bug is causing PNCDs corrupt previews, I think that must be something else. Jonathan Link to post Share on other sites More sharing options...
pgk Posted October 3, 2014 Share #31 Posted October 3, 2014 I think are probably the image ID problems that Wilson mentioned above. This needs Leica to fix in camera firmware update. I don't think that it has anything to do with Leica (or Canon) as it happens with both - its a glitch when copying files from one location to another and/or when the computer reads a drive with files which are 'old' and to me this indicates a more fundamental error which must have something to do with location/identification by the computer. As far as I can see it has nothing to do with the camera (my files are fully renamed anyway). The renaming uses Bridges, so whatever my problem is its down to software as far as I can see - and image handling software is still far from perfect - Photoshop has a few problems which cause me grief but I've learned to live with them (even in CS6 which I'm using at the moment).

CheshireCat Posted October 3, 2014 Share #34 Posted October 3, 2014 Tell me where to put a damaged DNG file. If you have a Google account, you can upload the file on Google Drive and then share the link as public. By doing this, only that file will be visible to anyone who has the link (until you delete the file, of course). You may also use DropBox or other similar free cloud storage services. Very convenient for tasks like this. Link to post Share on other sites More sharing options...
PNCD Posted October 4, 2014 Author Share #35 Posted October 4, 2014 Okay. This is a shared OneDrive folder called Leica DNG with full public access. I think! https://onedrive.live.com/redir?resid=FCCF3D3D661C8AC6!24843&authkey=!ABGZmXJjjwbC3UA&ithint=folder%2c There are two files named Santorini-0005.dng, one says it is a copy. There are files copied directly from the SD card to two different NAS systems. One is damaged and one is not. Link to post Share on other sites More sharing options...

Jaybob Posted October 4, 2014 Share #37 Posted October 4, 2014 Opening the files in Photoshop CS5 gave the same results. When I tried to use the Adobe Digital Negative Converter to "Extract Originals" it said "No embedded originals were extracted." Some cards inexplicably don't play well with certain cameras, copying schemes, drive arrays, and/or card readers. I wouldn't use that card/camera combo again. Sorry.

PNCD Posted October 4, 2014 Author Share #38 Posted October 4, 2014 One was damaged and one undamaged when I selected them. Now both are damaged. You can see the same two files in the first screen short as Santorini-0005.dng in the middle of the second row. One damaged and one undamaged. So what is the cause of this damage?

There are files copied directly from the SD card to two different NAS systems. One is damaged and one is not. Both files are corrupt, due to SD read errors. The files are corrupt in different locations, as the broken SD read reliability may be affected by external factors (such as temperature). Therefore different reads from the SD may produce different binary files. Note that the two files have different lengths, as one file (the "Copy") embeds the original JPG thumbnail, while the other embeds a thumbnail recomputed from the RAW data. SYNOPSIS Bin your SD card.
