  • NEF files are a proprietary image file format specific to Nikon cameras.
  • Opening them on Windows 10 isn't all that easy since you lack any native tools that can handle this format.
  • As such, you will need third-party tools to view, edit, and convert NEF files, software like Adobe Photoshop.
  • You can read even more guides like this on in our dedicated File Opener page.

NEF stands for Nikon Electronic Format, a RAW file format that contains digital photos taken by a Nikon camera. This format has each and every detail of the image as captured by the camera’s sensors, and has no compression or loss of quality.

The NEF file format stores metadata of the images such as the model of the camera itself, settings, lens information, and other details.

The main advantage of writing images in NEF file format to the memory card as compared to the TIFF or JPEG format lies in the fact that no in-camera processing post-processing isn’t permanent.

Stuff like the hue, tone, sharpness, or white balance is applied, but these are retained as instruction sets that come with the NEF file, and can be changed as many times as you want without affecting the original photo’s raw data.

Another advantage is that depending on the camera you’re using, the NEF file retains 12-bit or 14-bit data, which translates to an image with a greater tonal range than that of an 8-bit JPEG or TIFF file.

With Nikon’s Capture NX2 software or other imaging programs, the after-capture processing of NEF files gives you greater control over the final image than when JPEG or TIFF files are processed.

You can then save them as TIFF, JPEG , or as NEF again. Provided that the original NEF file is preserved, the digital negative remains untouched and processing doesn’t change the original instruction set.

It is exclusive to Nikon cameras, and sometimes it is referred to as digital negatives and is written to the camera’s memory card in either uncompressed or lossless compressed format.


How do I process NEF files in my camera?

Here are the steps you can take to process the NEF files in your Nikon DSLR camera prior to opening the file:

  • In the Retouch menu, find NEF in-camera processing feature.
    • This lets you process NEF RAW files into JPGs within the camera, and is useful for shooting RAW files or sharing a quick JPG
  • Adjust Picture Controls or change images from color options like Black & White (B&W) or Sepia, change white balance, exposure compensation and so much more
  • Once you’re done with and satisfied with the adjustments, preview it by pushing the magnifying glass button on the back of the camera
  • Select EXE when you’re ready to save the JPG file to your media or memory card
  • The original NEF file will be saved on the memory or media card so you can revert to the original capture when opening the NEF file on your computer

If you have the right codec on your PC, you can open or view NEF files without the need for more software. For Windows 10, you don’t need to install the Microsoft Camera Codec Pack as the codecs are built-in to the operating system, but should you want to add support for DNG formats, or others not supported, you would have to download a codec.

The Microsoft Camera Codec Pack enables viewing of a variety of device-specific file formats in Windows Live Photo Gallery and other software-based in Windows Imaging Codecs (WIC). Installing it will allow supported RAW camera files to be opened or viewable in File Explorerand is available in 32-bit or 64-bit versions.

NEF files can also be opened using software as the ones below:
