What is an NEF file?
The Nikon Electronic Format (NEF) is a proprietary raw image container exclusively used by Nikon digital cameras, structured around the TIFF (Tagged Image File Format) specification. It stores raw 12-bit or 14-bit data captured by the image sensor without in-camera processing, alongside extensive metadata including EXIF data, Picture Control settings, and lens identification. The format supports both lossless and lossy compression variations and encapsulates a full-resolution JPEG preview within the file structure for quick referencing.
How to open an NEF file
Microsoft Windows (with the Microsoft Camera Codec Pack) and macOS Preview offer native support for viewing NEF files. For professional editing and raw conversion, Nikon provides the proprietary NX Studio software. Third-party industry-standard applications such as Adobe Photoshop, Corel AfterShot Pro, and the open-source editor GIMP (utilizing Darktable or RawTherapee as a backend) allow for manipulation of the raw sensor data.
