Horizontal colored bands appearing in imported raw files

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?

Hello! I'm encountering this SAME issue, which is absolutely maddening.

My process:

I cull images in Photo Mechanic (which I uninstalled and reinstalled to rule that out as the problem). In this program all of the images look totally fine. Then I copy those images onto an external hard drive (I've switched hard drives 3 times now, so it is not a hardware issue). Next, I import into a new Lightroom catalog for each session (yes, I've checked if the catalogs are corrupt, but this issue keeps happening, so it can't be that). When I preview the images in the Library everything looks fine, but the minute I switch to the Develop module (no presets, nothing but the RAW file) the banding will immediately appear on several images.

I work professionally as a photographer and I cannot afford to have this problem keep happening.

I have replaced SD cards, and uninstalled and reinstalled Lightroom Classic 3 or 4 times, but this line banding keeps popping up. My husband works in IT and he has checked all of my hardware multiple times. What's the solution? I'll attach a photo of what it looks like on my side.

Any suggestions would be amazing. Thanks!

Here's what I would try, since mine was solve by removing my USB hub:
1. Open the same photo from the SD card but bypass Photo Mechanic. e.g., Just browse the SD, right-click, and open in Lightroom directly. Or browse in Adobe Bridge, right-click select "Open in Camera RAW." Is it still corrupted?
2. Use a different cable to connect your external hard drive. Get one that's Thunderbolt rated like this Belkin Thunderbolt 3 USB C to USB C 3.3ft/1M Long Data Transfer Power Cable with 20 Gbps Data Transfer Speed: https://www.amazon.com/Belkin-Thunderbolt-Type-C-Cable-F2CD081bt1M-BLK/dp/B01CEFESRO/

3. Make sure the firmware on your camera and lens are the most recent.
4. Don't use any USB hubs, plug straight from computer, to cable, to external drive.
5. You replaced SD cards, but not sure if you replaced your SD card reader. Remove it from the signal chain, (i.e. send photos wirelessly to your computer), or replace it with the highest quality one you can find.

I'm sorry I don't have a solution. I am having similar issues after importing some of my photos from my photos app on my MAC to Lightroom. That tells me it is lightroom. It is very frustrating. The original photos in my app don't have any streaks of weird colors anywhere.

Lightroom never changes your original images. The only known answer is that it is a hardware malfunction somewhere, could be camera card, card reader, hardware used to transfer to computer, bad hard disk, bad memory. You have to do some basic troubleshooting to isolate the problem. Some apps (perhaps the Photos app) display the embedded JPG in a RAW file, the RAW file is corrupted but often the embedded JPG is fine.

Getting a headache reading all this. One common thread is a good 95% insist not hardware must be Adobe.

well, have you considered the following simple approach to attempting to isolate a possible issue with USB, be it a device, a cable, or a port.

First off, if you have a laptop, one with a Card reader, yep, SD only, disconnect ever single connected USB device, your mouse, your keyboard, an external card reader, that microphone, that external hard drive, the speakers, a headphone, etc, etc.

Second off, shut the laptop off, then turn it back on, just rebooting will not suffice, need to accomplish a cold boot.

Now, create a brand new catalog, this one on your hard drive. But yours on the external hard drive. Let me be rude, as apparently rude is called for, yes, internal hard drive, remember no external usb devices, just yet.

Go and shoot some images, many images, at least 10 per every usb device you had connected.

in that nice clean, boarding, empty lightroom catalog, accomplish a proper import from within Lightroom.Do they look Ok? If not, still continue with the next step if applicable to your available USB devices.

next up, an external card reader? Connect it, try a few more images, if the previous step came up AOk, and this step fails, guess what, possible bad card reader. If the other way around, sure hope it is not your internal card reader, see repair etc.

next up, keyboard, repeat, recommend internal card reader if SD.

mouse, repeat,

external hard drive, repeat (no, still that new catalog on internal drive)

on and on untill I’ll you run out of whatever was connected before all this mucky muck.

if you found a suspect device, consider the attached USB cable, go buy a new one.

NOTE, USB cables may work fine for one device and fail for another, digital cameras for one get very very picky

For non SD card users, CF and the like, yep, you start with the card reader plugged in.

For desktops, of course, you will need your mouse and keyboard connected.

extra note, do not forget any Bluetooth dongle for a wireless mouse and/ or keyboard, that communicates to the USB port(dips) after all.

I had a shoot earlier today and panicked when I had a bunch of these lines on my RAW files after importing to LR from my SD card reader. As much as I'd like to blame Adobe, I can't. Same thing happened when I imported them into Capture One Pro from the same reader. When I swapped out my card reader and used a different one, everything imported just fine and the lines were gone. This was definitely a hardware problem for me.

Does anyone relate this to the speed of the memory cards? I have a bunch of older ones that never presented this kind of problem, with the same card reader. But i bought two faster memory cards recently 50mb/s and 120mb/s and both of them are presenting these color bands wherever I transfer them: Lightroom or Finder or Photoshop directly. I lost my camera cable (dumb), but I am considering buying a new one just for the worth of a test.

So, any thoughts on that?

It's worth a try, especially since another possibility is that the card reader itself is causing this problem. If you can do a test with one of the older slower camera cards, that would help narrow down the possible cause as well.

I use Nikon D7200 with a Lexar 32GB card and I just transferred my vacation pictures in to mac and then imported in to lightroom. When I first transferred in to mach and looked the preview, pictures were fine. When I imported them to light room as a catalogue I got the colored streaks on all the NEF pictures. The same pictures were transferred to windows where LR was not installed and the pictures were perfectly fine. It should be a problem with LR. Did anyone find any solution for this from the Adobe experts? Please let me know.

There is an embedded JPG preview in the file that can be uncorrupted while the actual RAW image in the file is corrupted.

That is why different viewers show uncorrupted images from the JPG preview while Lightroom, when it renders the RAW image, shows corruption.

You need to determine which piece of hardware is causing this corruption. It could also be that whatever hardware was used to transfer the image on the 2nd computer did not cause the corruption, while the hardware used to transfer the image to the first computer did cause the corruption.

I used the same card reader both for mac (where LR is installed) and on to windows PC (where LR is not installed). I am getting clear pictures in PC and colored bands in Mac

I've had that problem with Sony cameras. Importing raw files directly from the camera as opposed to a card reader, solves the issue.

Your card reader is malfunctioning and this is the cause of the corruption.

I've tried several card readers. Not sure what the problem is but importing from the camera has worked for me.

This is getting really weird. I am tired of this issue. It does not matter what camera (D2Xs, D3, D3s, D4s, D7200, D800, D810, D500) ALL show the problem.
Six (6) different computers, over 50 different CF, SD, XQD cards

Mac OS (various versions)

Windows (7, 8, 8.1, 10)

Different manufacturers

Different versions of Adobe Camera RAW and Lightroom and Bridge

The ONE common is ALWAYS Adobe product.

SOME NEF files are corrupted, some are not. I have converted some of the "corrupt" files in On-line converter and get a fine output. However, I can;t prove the result is the embedded JPG or an actual processing of the RAW data.

I have tried every known method since I started having these problems. I also have tried copying the files from the CF card first to a Hard Drive.... same problem and still random

BTW, also many media from HDD, SDD, SAN, NAS, etc. Even DVD and CD burned for kicks LOL

Thanks "Adobe" for your help. YOu have the resources to get to the bottom of this. Your end users can't possibly do the deep research you can. We are paying customers who expect some help. This is not fake and contrary to what others may say, does NOT have a known solution.

Thank you!

Sincerely,

We're not Adobe in this forum, gonzalu, if it is a problem with LR (which I doubt), we can't fix it, we can't add more resources to the task, we can't do anything about it. Maybe you should actually contact Adobe on this matter. Lightroom Classic CC | Photoshop Family Customer Community

But reading your description of the problem, you don't seem to have tried isolating or running diagnostics on the different pieces of hardware involved (card reader or USB cable, bad hard disk, bad memory chips) to confirm or rule out hardware problems. These problems almost always boil down to a hardware malfunction somewhere, I am not aware of any time when the problem was the software.

dm_paige,

wanted to say thanks. I read through some of these comments and at first I was panicking thinking the camera was broke. But then I tried transferring to another drive and went straight into Lightroom with no problems. Before that I was getting extreme corruption, my images looked like they had gone though Instagram on acid. Anyway your advice worked and I’m replacing the faulty drive. Thank you so much for your knowledge.

I am having the same issue transferring RAW images from Sony A7ii to Lightroom CC via card/adapter onto my new Macbook Pro. The problem does not seem to happen if I transfer via Bridge. Since Lightroom is my go-to I certainly hope Adobe fixes this issue quickly.

Once I got a new card reader (Lexar CF/SD USB 3.0) this issue cleared up for me. I haven't had it happen since then except using a faulty MicroSD adapter once.
