What is NEF File?

The NEF photo format was created by Nikon, stands for Nikon Electronic Format. Photos captured by the Nikon CCD camera will be stored in this format. Like many other camera-created file formats, the NEF photo is a RAW image. 

The RAW image file contains more extensive data than compressed photos and records the maximum amount of information obtained from the camera's optics and sensors. Some professional photographers prefer to shoot in RAW because RAW images allow them to process and edit photos more freely without compromising the details and quality of the photos.

Although almost every camera manufacturer provides a RAW image file format, there is no standard format. When shooting with different brands, you will encounter different file formats. For example, Canon saves RAW digital images as .CR2 or .CR3, while Sony saves RAW images as .ARW.

How to Open NEF Files?

Since the NEF files are not common image file formats, you might need to download additional software to open NEF images.

For example, Nikon has developed two software - Capture NX 2 or ViewNX 2, to help users open NEF files. You can search and download either of the two. The former can only be obtained by purchase, but it gives users a 60-days free trial. The latter one is free for anyone to download and install to open and edit NEF files.

What's more, there is much third-party software that also enables users to open and edit NEF files.
