    Horizontal colored bands appearing in imported raw files

    sevenc Level 1

      I just now started to have mostly magenta horizontal lines or bands appear in imported a Sony Nex 7 ARW files. When opening the same file with Sony’s raw converter or DXO Pro, the bands are non existent. I have noticed that sometimes but not always, the bands will disappearing in LR after I examine a photo by clicking on it to enlarge a selected area and the loading finishes. Exported photos will have the bands. Also, If I first open the files with IDC or DXO, the file will then import into Lightroom without the bands. I have run diagnostics on the SD card and the hard drive with no errors showing up. Running LR5.4 on a Macbook Pro. I’m totally confused. Any enlightening comments would be greatly appreciated. Thanks.


      These artifacts are exactly like those in the post : Why do I get Colored bands on some images in LR4 and LR5, but not in Aperture?

          Can you supply one of the raw images that shows this problem?  Use http://www.dropbox.com/ and post a public download link, here.

            The raw data is also corrupt in RawDigger, which uses a non-Adobe rendering engine:

            So the question is why is Aperture able to render it.  If Sony has a way to work around the corruption, then perhaps Sony has given something to Apple that Aperture uses to do the same thing, but perhaps both programs are merely showing the embedded preview in lieu of the raw data.

              It doesn't render correctly in Aperture; I just tried on 3.5.1, and it shows the same banding. It also shows exactly the same banding using the latest version of AccuRaw. Corrupt file, probably an SD card issue.

                Thank you for the help!  I don’t have Aperture, I was using DXO Pro and the Sony IDC. The imbedded preview is black and white, so I don’t believe either of those are showing me the preview.I have tried a couple of different card readers with the same result. Hmmm.

                  Another interesting thing is that my Windows 8 (not shown) and Jeffrey's Exif Viewer website (below) show the embedded previews as black-and-white, not color, and normally this site gives the option to download the raw data as a TIF but that option is missing:

                    OK, its getting a little stranger. I tried a different SD card and had the same result. I then deleted the imported files from my disk and reimported the same files from the same SD card and the banding was gone. I tried this several times and every time the results were the same.

                      Yep, this file is broken in Photo Ninja, DxO Optics Pro 9 and Capture One 7 Pro too.

                        If importing from the card results in different amounts of corruption at different times then something may be wrong with the items involved in the transfer, from the reader/cable or anything on your computer, itself, including memory.  The file you uploaded to Dropbox had the banding baked in, but perhaps the files on the SD card are not bad, only the transfer process, though maybe the card is iffy and sometimes it works and sometimes it doesn't. 

                         

                        I'd suggest you run a memory diagnostic to thoroughly test your computer's memory.

                          I think your suggest is excellent, however I have run diagnostics on the computer memory and hard drive and everything comes up clean. (the memory tests ran all last night with no failure)

                            I have the EXACT same problems when importing .RAF files from my Fujifilm X-T1 via a USB card reader (USB 2.0) on my MacBook Pro 13" Retina (late 2013) with OS X 10.9.3 in Lightroom 5.4. (I did not purchase the X-T1 until after I updated to 5.4, so I can't speak of whether this happens in other versions of LR)

                            I second sevenc's suggestions that this is NOT a hardware issue - I have tried 5 different SD cards, all formatted either on my computer or in the camera, reformatted several times (low-level format) and it STILL happens! Never with the JPGs, only with the RAW files.

                            However, doing a straight file copy from the SD card (in the card reader) to the hard drive before doing the import works fine - no artifacts!

                            Ditto if I use the internal SD reader (an internal USB3.0 connection) on the Macbook, no purple bands.

                             

                            It is apparently unrelated to the OS, since this is happening both in Windows and OS X. I have posted a more detailed acccount here:

                            Lightroom 5.4 - "glitches" on my RAF->DNG conversions from X-T1 - Fuji X Post Processing - Fuji X Forum

                            One of the members of that forum has seen the same happening with Panasonic RAW files, but only when an external USB drive was connected at the same time.

                            When the external drive was disconnected, the images imported normally.

                            BTW, my Canon files import just fine, using the same SD card, the same USB card reader and the same computer - no glitches....

                            The most likely thing happening (my opinion) is that the Lightroom import process somehow interferes with the USB connection. It doesn't really make sense, because I am sure Lightroom uses the standard OS I/O file routines, but it seems to be the most likely issue. Is there a chance LR uses its own code for reading files off of external drives.

                            Other software (Aperture, Preview, Image Capture, Raw Photo Processor 64 or PhotoNinja) can import fine, whether the card is in an external card reader or not - no artifacts.

                            I have seen it the same issue described with Panasonic files on LR 4, so it does not seem to be limited to LR 5.4

                            Re: Why do I get Colored bands on some images in LR4 and LR5, but not in Aperture?

                             

                            Anyone care to shed light on the issue and what could be going on here ? It seems the more obscure raw formats are affected (Sony, Panasonic, Fujifilm) and that Canon/Nikon users do not experience it (at least I haven't found it described online).

                             

                            This is a serious bug, because unless you do a re-import of the RAW/RAF file, the image data is permanently corrupted. It is not an issue of corruption of the embedded JPG preview , it is the RAW file itself. Once it has been imported by Lightroom, it displays the artifacts in other programs as well (Aperture, Preview etc)

                            Trying to convert the image to another format, e.g. TIFF, JPG, BMP the artifacts are still there.

                             

                            I hope this is taken seriously by Adobe, as it is a critical issue for those of us who are affected. I can work around it by copying the files to my hard drive first, but it shouldn't have to be this way....

                              Same issue (Mac Pro, Panasonic GH4, SD is USB SD reader: Xit Photo reader").

                               

                              1. Import directly from USB Xit Reader to LightRoom - Problem lines in all images
                              2. Copy from USB Xit Reader to HD, and import into LightRoom - Good Images
                              3. Import directly from USB UniTek MultiReader into LightRoom - Good images

                               

                              The Xit SD Reader was a freebie that came with other gear I purchased.  I looked it up and the manufacturer site says Xit is an SD/SDHC reader (SDHC reads up to 10 MBs).  The UniTek SD/SDHC/SDXC reader supports up to 300 MBs.   The MAC Pro USB 3 speed is (reported in practical terms) roughly ~350 MBs. The MAC SSD HD has reportedly been clocked at ~1200MBs.

                               

                              Since everything OS related read both SD readers successfully, one has to believe LightRoom has a driver/import/buffering problem from certain, potentially slower, USB configurations on MAC.  I don't know if LightRoom has this problem on Windows. 

                               

                              Barring LightRoom providing a fix, using a fast 3.0 USB reader might be the only solution (or, ugh, copy to the internal HD first).

                                I am having this exact issue, and the images are getting ~dramatically~ glitched; half of them opaque with hot pink color, the other half fully banded with purple or yellow. 2014 MacBook Pro 15 inch 2.5 GHz Intel Core i7, Canon 5d Mark II, Lightroom 5 CC. All brand new hard/software. No issues importing to iPhoto (ugh), or copying to hard drive, but this is insane! I should be able to use lightroom! Has there really been no action on this issue? Feel like I deserve a refund on adobe softwares.. long time adobe customer, very disappointed. I've lots tons of irreplaceable images of Antarctica and Iceland because of this bug.

                                  This is caused by a hardware malfunction

                                   

                                  could be your camera card, card reader or cable/usb port, hard disk or memory

                                      i've read the previous posts, and i understand this is likely an issue with the card reader i purchased (albeit for an insane $70, which makes me furious)-- but that is not currently fixable. i bought a brand new card reader, cf card, and usb cables because i'm currently on a month-long residency in remote northern iceland, where it is not only difficult but impossible to buy any new hardware. post from the US will take over a month. yes, i probably should have brought backup cables or card readers, but what can i say? i had just bought a brand new camera, updated my creative cloud apps fully, was working with a less-than-year-old macbook pro, and i'm not a photographer by trade, so i'm used to having my equipment, um, work.

                                       

                                      barring my ability to isolate/purchase new hardware for the next month, but needing to dump my cf card once a week to clear room for more (once-in-a-lifetime) pictures, what's my best bet of not corrupting the files during the transfer over?

                                        Every camera I know of comes with a cable to connect to the computer. You could try that. Yes, it will transfer photos slower than a card reader, but (assuming the card reader is the culprit) you will get un-corrupted photos.

                                          Do an experiment:  Copy the same set of photos multiple times in multiple ways:  camera-cable-computer, card-reader-computer, and using the OS (Finder/Explorer) and using LR, that's four different variations.

                                           

                                          If the photos have the same errors each time, then either the camera or the card are likely at fault.

                                           

                                          If the photos have different errors or different photos have problems each time then something from the cable to the computer ram are the problem, but not the card or camera, and you can try to get an error-free set of photos by copying multiple times, and combining several copy runs.

                                           

                                          This will help you determine which element is failing and whether there is any hope of getting error free photos or not.

                                            I just encountered the same issue with my D800, copying files over from the camera (connected via USB 3.0) through Lightroom CC, storing the copied files on to an external hard drive (Seagate usb 3.0 750 gb). From what I've read it seems the conflict may be in transferring data via a usb 3.0 source to a usb 3.0 destination using the same usb controller/hardware. I'm using a PC btw. This is the first time I've transferred files from a 3.0 connection to another 3.0 connection through LR, and this is the first time I've encountered these artifact. I'm guessing that Lightroom is the culpret, as it's the program handling the data transfer, which appears to be misplacing some data points every so often in translation between devices. I'll try recopying the files tonight via the same cabling, but this time using explorer to transfer the files...and see if anything gets twisted... if not, it's likely LR.

                                              I'm guessing you didn't read the rest of the thread, because then you would see that everyone is suggesting you have a hardware malfunction somewhere.

                                              Lightroom uses your operating system to move photos from camera card to hard disk (or for any other move or copy).

                                              You'd be much better off using different hardware.

                                                I read the thread ( as well as this oneLightroom corrupting RAW files? Hardware issue?), and noted that it's likely hardware related. But some hardware works only as well as the software instruction it's processes.  Pointing toward popular suggestions does't make something the answer until verified with definitive testing and rigor, and so far I have't come across such info that answers the question outright.  My thought is that it's hardware related, but my notion was that it MAY be how LR is handling the hardware. Perhaps other software will create similar artifacts using said hardware, though I've not tested this yet, but neither have I encountered it. I would like to better understand how LR is instructing the OS to transfer files, if you have more info on that I'd be much obliged if you would share your source/knowledge toward it. I'll be testing multiple configurations of software, cables and cards, and hardware, and see what turns up in the mean time.

                                                  Lightroom doesn't interact with the hardware directly. It issues operating system calls every single time. So if there is file corruption, it cannot be Lightroom.

                                                   

                                                  Every thread goes the same way. People state its a hardware issue, the poster argues, and then eventually after lots of debate and arguing, the original poster finds out it is a hardware issue. It is never anything else, nor is there a plausible explanation for how anything other than hardware can cause file corruption.

                                                   

                                                  So, you would be wise to test your hardware chain, from camera card all the way through hard disk and computer memory. If you don't think that's the cause, that's fine, but I'm afraid its the only answer that has ever been found, and most likely it is the only answer you will get from this forum.

I am curious about this because it seems to have started shortly after a recent update to Lightroom CC. This is certainly something worth keeping an eye on, I will no longer be using lightroom to transfer anything.

                                                        It's your hardware, there is a malfunction somewhere, Lightroom does not modify your photos in any way.

                                                          I was brought to this forum via a search for a solution to a similar problem it a batch of photos from a recent location shoot. Background:  At a recent photo shoot several thousand photos taken with a D800. The shoot consisted of several sets. After each set, the full sized NEF were copied from SD to an external SSD via MacBook Pro 2014 using the computers internal SD port and USB3 cable to the external drive. A replacement SD card was placed in the D800 before each new set. Each set was uploaded to a new folder separating them From the other sets. At the location a preview the NEF using Finder revealed no abnormalities. Back home, Lightroom CC is used to process this shoot. Before importing, a new Catslog per set is built and then each set imported. All of the sets imported without incident. All sets were set to export JPEGs for client reviews. They were saved on a second SSD. it was during the upload of JPEGs to a Cloud that I noticed the abnormalities in one set of photos. Almost every photo in that set had color streaks. I went back to the SSD to discover not only the JPEGs with streak the NEF had the same damage too. All the other sets of photos show No signs of damage. This is isolated to only that one set of photos. You should know the abnormalities have different patterns. Some are diagonal. Some are horizontal. The randomness is curious in itself. I cannot rule out the one SD was damaged, incorrectly connected, or other posibiliries. My question are:

                                                          1.  How do I begin to repair this batch of files?

                                                          2.  Is there any program out there designed to extract repair the embedded JPEG files from the parent NEF.

                                                          3.  Is there a program that can repair JPEGs affected by this type of digital corruption?

                                                          Thx...

                                                            If you will read this thread, there are many suggestions to help you find the cause of this corruption.

                                                             

                                                            The files cannot be fixed. You would need to re-import them from the camera card, avoiding the piece of hardware that caused the problem.

                                                              I thought it was an isolated problem, but I can see it happens to almost every camera brand. I own a Nikon D810 and a D750, it has happened to me on several occasions. I'm a bit of a backup freak so I do a backup every time I can as often as I can, I even use my second card as a backup, so fortunately I have had a backup file every time it happens. One of the most painful files I got corrupted was a photo I took several months ago so I had erased the files from the SD and CF card. Luckily I got the same file from my backup hard drive and it was good, I even changed my iMac Hard Drive for an SSD and it's happening again. I've tried different card readers (2.0 and 3.0), different cards, CF cards and SD cards and it's happened to me again and again, it even happens in my laptop. If there is a hardware causing the problem, must be a lot of hardware in a lot of different places and both Windows and Mac OS for over a year as I can read.

                                                               

                                                              Funny thing, the files that you copy from the SD/CF cards to the hard drive don't get corrupted, even if it's the same file, imported from the same card to a different hard drive, or imported again from the card (it would say that the hardware fails randomly)

I'm using an external card reader as there is no internal one on these laptops. If I import using Lightroom I have the lines. I've happily just discovered that if I use finder to copy the files from the SD card to the appropriate location on the LaCie harddrive then import them to the catalogue by adding rather than copying, then no lines. I'm still to experiment with "corrupted" files that exist only on the hard-drive but hoping even these can be moved, deleted then added again without said lines. So seems to be a Lightroom issue?

I copied the files over manually and the problem disappeared. I am not sure what caused the issue but it was happening legitimately only through Lightroom import. I am going to see if copying them to disk and then importing and moving/importing them on the computer has the same artifact issue.

Stripes across the image. It is definitely NOT a hardware issue contrary to the patronising posts above. I know this because jpeg's produced by the mavic at the same time using the same input device are not affected when importing into Lightroom. Also if the DNG files are copied onto the hard drive first and then imported from there into Lightroom there are no stripes and no problem. It is definitely something that Lightroom import is doing to the Raw files direct from the card. This was not a problem until recently (using the same hardware) so I imagine it may be to do with a recent Lightroom update.

Beware though that any attempt to import directly into lightroom when you have this problem permanently stripes my images, even if I subsequently try the work around. N.B I shoot Canon as well and there's no problem with those files.

Here it's the exact same image after being imported to LR and in the back up drive, exact same file, from exact same CF card.

Once the file showed up corrupted in lightroom, when I opened it in Raw it had the same banding. I unfortunately didn't back up the images so I'm scrambling. I went to Photoshop and am processing the images to PSD files to get them out of raw and it seemed to have worked, I'll see once it's done. I'll try the above suggestion about updating the metadata to see if that works. Crossing my fingers, if it doesn't work, then I'm not using LR again until I hear it's fixed. :/
