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.

What is a GIF file?

The Graphics Interchange Format (GIF) is a bitmap image format developed by CompuServe in 1987, distinguished by its use of the Lempel-Ziv-Welch (LZW) lossless data compression algorithm. It supports up to 8 bits per pixel, allowing a palette of 256 distinct colors selected from the 24-bit RGB color space. The GIF89a specification, introduced in 1989, added support for transparent backgrounds, animation delays, and application extensions, establishing it as a standard for simple web animations and low-color graphics.

How to open a GIF file

GIF files possess near-universal compatibility and can be opened natively by all modern web browsers (Chrome, Firefox, Safari, Edge) and default operating system viewers like Microsoft Photos and Apple Preview. No third-party software is typically required for viewing. For editing frame-by-frame animations or modifying color palettes, raster graphics editors such as GIMP, Adobe Photoshop, or online tools like Ezgif are required.
