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 Re: 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.

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 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 Fo...

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

And you will be able to - once you've tracked down which piece of hardware is failing and fixed it.

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.

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.

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 Also had these issues this past week while on vacation. Every time I used Lightroom CC to facilitate the import of photos I would get a certain number of these glitched out banded photos. Using the same (built in SD card reader) on my MBP I would also Manually transfer the same NEF files from my d750 to a backup file on the same SSD internal disk and have ZERO corruption, every file I manually transfer is fine. 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.

Hello dj_paige, to my awareness, this doesn't seem to be a hardware issue from any end. I had the same issue with my licensed LR classic CC while importing *any* image (either JPEG, RAW, NEF, whatever image format it supports) whether from the camera or a simple one downloaded from the net to the local D drive. I'm using Windows, and have tried switching the windows version too. Nothing seems to solve the issue. Obviously, my local drive doesn't have any issue as it's a 4-month old new hp laptop manufactured a year back. There is definitely issue with the software in that it seems to include RGB horizontal lines with the actual image distorted on the background with a silver black watermark on it. It happens only when any image is already imported and the "develop" tab is selected. Just importing doesn't cause any harm. Reading all the thread issues people are facing, I think I'm the first one writing even a JPEG downloaded image is not getting to be developed with LR for this weird issue.

You just state this but provide no evidence.

Not a convincing argument at all. New hardware can malfunction. You don't state you have checked computer memory, or checked the hard drive.

Maybe you could also state the actual problem you are having instead of saying "same issue".

I had the same problem and looked it up, finding this thread which was useful, including in knowing I wasn't alone!

In my case I had imported nef files from SD to a PC laptop. I had then exported the files as a semi-edited Lightroom Classic CC catalog to a desktop PC. It was here that I noticed the problem on half a dozen files, one of which was important. After a minor panic, I went to the laptop, found them uncorrupted there and exported them as original nefs and reimported them to the desktop. Problem solved.

Luckily I hadn't deleted the files from the laptop, however if it had been the transfer from the original SD cards and I hadn't noticed then not so good as they were formatted as soon as a second backup had been made.

My conclusion is that somewhere between the laptop and the PC transfer of the catalog (via a hard drive), something has occurred in the actual transfer. I can't see how it can be anything other than a hardware problem (cable may have been poorly connected/damaged etc.). I've started running chk dsk - 14 hours to go 😞 - on the intermediary drive as it may well be a corruption on that, but for what it's worth - though I'm no expert - I'm fairly sure it's a hardware issue.
