What is a .nef file?

NEF is a RAW image format used by Nikon digital cameras. It contains minimally processed data from the camera's image sensor, preserving a high level of detail and dynamic range. Unlike JPEG files, NEF files are not compressed with lossy compression, meaning no image data is discarded. This allows for greater flexibility in post-processing, enabling photographers to adjust settings like white balance, exposure, and contrast without significantly degrading image quality. NEF files essentially act as digital negatives, providing a starting point for extensive editing and manipulation. They are particularly favored by professional photographers and enthusiasts who demand the highest possible image quality and control over the final output. Because NEF files contain unprocessed data, they are typically larger in size than JPEG files. They also require specialized software for viewing and editing, as standard image viewers may not be able to interpret the raw data. The format allows for non-destructive editing, where changes are saved as metadata alongside the original image data, ensuring the original file remains untouched. This makes it possible to revert to the original image at any time.
