What is it?

NEF (Nikon Electronic Format) is Nikon's proprietary RAW image format used across Nikon DSLR and mirrorless cameras. NEF files contain the raw, unprocessed data captured directly from the camera sensor, before any in-camera processing such as sharpening, noise reduction, or color adjustment is applied. This gives photographers complete control over the final appearance of the image during post-processing.

NEF files are based on the TIFF container format and support both lossless and lossy compression variants depending on camera settings. The 14-bit color depth captures a far wider range of tonal and color information than the 8-bit depth of JPEG, which means significantly more detail can be recovered in shadows and highlights during editing. Nikon's software and most professional editing tools support NEF natively.
