What is a NEF File?
A NEF file is created by the Nikon digital SLR cameras and saved as it was captured in an uncompressed format. The NEF file also contains metadata about the image, including information about the camera and the lens that was used to capture it.
NEF files support 12-bit or 14-bit data, depending on what camera was used. These images can be used in image-editing software to adjust them. Any changes made to the images are then stored in a separate file within the NEF file as an instruction set, which means that the image can be restored to an earlier state if and when required.
