What Is A NEF File? What Is It For And How To Open One

This abbreviation stands for Nikon Electronic Format and is only used on Nikon cameras. A file with the NEF extension is a Nikon RAW image file.

Like other RAW image files, NEF files contain everything the camera captured before processing, including metadata such as camera and lens model.

The NEF file format is based on the TIFF format. This file format is also known as Nikon Electronic File. The same acronym is also used for other technical terms such as NEF.

What is a NEF file?

A NEF is a raw image file that stores the data exactly as it was recorded by the camera sensor. NEF is a proprietary Nikon format which is only compatible with Nikon software, codecs and plug-ins.

NEF files are typically large, but some non-professional Nikon cameras use compression to reduce the size of NEF files.

NEF file compression, which is based on algorithms that only slightly reduce image quality, can be disabled on professional and semi-professional models.

NEF files not only store image data, but also the metadata and full details of the camera used to take the image, including the creator, copyright, GPS data, and image parameters that can be modified, such as

• Exposition,
• ISO ASI,
• contrast,
• tone,
• white balance
• Tone and saturation

NEF files also store a history of all changes made to the image during editing, allowing the user to undo changes. RAW image processing can be compared to the development process of analogue photographs and the RAW image format, including NEF, is sometimes referred to as a digital negative. Processed RAW images can be saved as NEF files or exported to another more common format such as JPEG.

How do I open a NEF file?

There may be several reasons for problems opening NEF files on a particular system. Fortunately, the most common problems with NEF files can be solved without extensive computer skills and, most importantly, in just a few minutes. We have compiled a list to help you solve problems with NEF files.

Step 1: Install ViewNX software

The most common cause of this problem is that your operating system does not have the appropriate software to handle NEF files. You can solve this problem by downloading and installing ViewNX or another compatible program such as CorelDRAW, Adobe Photoshop or PaintShop Pro.

Above you will find a complete list of programs grouped by operating system. One of the least risky ways to download software is to use the links provided by official distributors. Visit the website of ViewNX and download the installer.

Step 2: Update ViewNX to the latest version

If even after installing ViewNX you are still having problems opening NEF files, you may have an outdated version of the software. Check the manufacturer's website to see if there is a newer version of ViewNX.

Software developers may also update their applications to add support for new file formats. This may be one of the reasons why NEF files are not supported by ViewNX. The latest version of ViewNX should support all file formats compatible with previous versions of the software.

Step 3: Assign NEF files to ViewNX

If the problem in the previous step is not resolved, associate the NEF files with the latest version of ViewNX installed on your camera. The method is quite simple and it does not vary much between OS.

Select the first application in Windows

• Right click on the NEF file and select Open with.
• Next, choose Select another app and open the list of available apps by clicking Other apps.
• Lastly, Select Browse to find another app on this computer, point to the folder where ViewNX is installed, check Always use this app to open NEF files and confirm your selection by clicking OK.

If the file is infected, the malware in the NEF file will make it difficult to open. Check NEF file and your computer for malware or viruses. If the scanner detects that the NEF file is unsafe, follow your antivirus program's instructions to neutralize the threat.

Check that the NEF file structure is not damaged

If the problematic NEF file was obtained from a third party, ask them to provide you with another copy. Errors may occur when copying the file, resulting in the file being incomplete or corrupted. This may cause problems with the file.. The download process of a file with NEF extension may stop and the file data may be incorrect. Please re-upload the file from the same source.

Verify that the logged in user has administrator rights

Sometimes the user must have administrator rights to access files. Skip from current account and log in to an account with sufficient access rights. Then open a Nikon RAW image file in electronic format.

4. Make sure your system supports ViewNX

If your system is heavily loaded, it may not support the program used to open NEF extension files. In this case, close other applications.

5. Check that your operating system and drivers are up to date

Updated systems and drivers not only make your computer more secure, but may also resolve problems with RAW files in Nikon electronic cameras. One of the available system or driver updates may resolve problems with NEF files associated with older versions of the corresponding software.

In Lightroom, Camera Raw is part of the import process. Both programs allow you to import a NEF file, edit it, and then save or export from NEF to JPG format. You can save them in TIFF, PNG, and even GIF formats.
