Summary: NEF unique format consists of the RAW data of an image, along with an instruction set that provides extensive image editing capability not available with other file formats. With a NEF file, the original RAW data of an image is never changed. So it’s a bit more complex to repair than other formats. This article shows how to repair them with ease.
‘I had captured beautiful locales of Caribbean islands with my Nikon D850 camera. Over two hundred photos were shot in RAW format (.NEF files). Back home, when I transferred the pictures to my system, most of them were either not opening, or were distorted. I tried different programs to repair NEF corrupted files but without success.
I cannot imagine losing these photos. Please help?’
Nikon Electronic Format (NEF) is used by all Nikon cameras to shoot in RAW. They are unprocessed pictures of high quality as perceived by the camera sensor. Shooting in NEF format gives liberty to photographers to enhance and creatively play with the images in the post-editing stage.
Naturally losing such photos can be seriously annoying.

Other manual ways to fix corrupt raw Nikon NEF files corruption
If the Nikon camera photos are not opening in one program, try opening them in another, such as Gimp, Nikon ViewNX, IrfanView, etc.
If the NEF files are not opening, convert them to another format using online image file converters. Make sure the program you are using to open NEF files is updated.
For instance, if a NEF file fails to open in Photoshop and displaying error, ‘Unable to open NEF file in Photoshop’, convert it to DNG format by using a free online image converter tool.
To view all kinds of camera-specific file formats on your computer, you can download the camera codec pack offered by Microsoft.

Noise, chromatic aberration, grains, and other distortions in the photos shot from any Nikon camera model, can be fixed in image editors that support RAW files like Adobe Photoshop Elements 11, Gimp, Lightroom, DxO Optics Pro etc. However, these photo editing software cannot fix corruptions caused due to SD card problems or disk errors. To fix grey bands, tiles, invalid file structure, file system errors, or corrupt header issues in NEF image files, Stellar Repair for Photo is the recommended solution.
You can also use Capture NX2 or Capture NX-D, the official Nikon photo editing software to correct corrupt NEF files.
When the PC gives ‘Memory card error’ making the NEF files in the card inaccessible, you can restore the photos by CHKDSK in command prompt. CHKDSK command scans for bad sectors and fixes the logical errors in the storage media.
Follow the below steps to perform CHKDSK:
| Tips to protect Nikon NEF files from corruption • Use Class 10 memory card from a trusted manufacturer • Ensure continuous power supply during transfer of NEF files • Do not shoot when the camera SD card shows low or full storage • Do not use your Nikon SD card in multiple devices • Do not shoot in low camera battery • Properly insert/eject the SD card from the camera and computer |

Hi I bought your software to get my files off my corrupted SD card, however they will not open I get a message to say that the file format is incorrect – do I now have to buy Stellar Repair for Photo to access the images?
A prompt response would be appreciated – thanks
Hi Helen,
The ‘Unknown JPEG Format error’ usually appears when the files get corrupt or the drive on which they are saved is damaged. In order to repair your corrupt images, you can use Stellar Repair for Photo.
I am wondering if your software actually “repair” the nef file (I mean I will be able to use the nef after repairing process) or it just is able to extract a jpg from the nef.
All the texts I have been reading from your site explain that just a jpg file is save from repairing process (and it is not a repair of the nef IMHO)
Hi Javier,
Stellar Repair for Photo repairs Nikon NEF files and saves them in JPEG format, which is usable.
Dear Sumona
I have now – several times – tried to run the scan and recovery of some corrupted NEF files from both the computer and the SD card. The program tells me that is has recovered the NEF, but the folder is empty and no thumbnail is blank, the JPG files are all gray. What am I doing wrong ??
Hi Steffen, We would like to inform you that the software works on the preview basis, however, if the preview is not available then repairing is not possible. you can try the advance repair to repair the NEF file by selecting a sample image made from the same device. Kindly confirm the reason for the corruption for these files so that we can check for any alternate solutions. More information you can contact our support team through email support[@]stellarinfo.com or call +1-877-778-6087.

Hi Peter, We would like to inform you that, the software works on “what you see is what you can repair”. That means the files will be repaired in the same manner as you were able to see them in the preview window after the scanning is complete. However, if there is any discrepancy in what you are able to see and what has been repaired then please send us through email support[@]stellarinfo.com the screenshot for the preview window after the scanning is complete along with the screenshot of the repaired file.
Thanks for addressing this very problem and providing the solution. It worked for me and fixed blurriness from my pictures which photo editor couldn’t do.
