The Nikon Df RAW files use the extension .NEF. This file stores all data from the camera including raw output from the image sensor. To support the Nikon Df, the program you are using must be updated to read the new camera model and information. Update your image editing or viewing program to a new version (if available) or use a RAW image converter to be able to open and edit your RAW files from you Nikon Df.
Current programs that support the Nikon Df RAW .NEF image file format:
ViewNX2 – Version 2.8.1 is included with the Nikon Df and will open the RAW .NEF files. You can then save the image as a as TIFF or JPEG. You can download ViewNX2 from Nikon.
CaputreNX2 – this program is a professional-level editor from Nikon. It is fully compatible with the Nikon Df RAW (.NEF) file format as of version 2.4.4. The update for CaptureNX2 is available for download 2.4.4 update If you own the old version of Capture NX (version 1) you can buy a discounted upgrade to NX2.
Adobe Photoshop Lightroom 5 – Adobe has released version 5.3 of Lightroom which now supports the Nikon Df. The update for Lightroom 5.3 can be downloaded for Windows and Macintosh. Lightroom 4 and earlier will not be updated to support the Df, but you can use the Adobe DNG Converter to converter to .DNG format and then open using Lightroom 4 or earlier.
Adobe Photoshop CS6 and Photoshop CC – These programs use Adobe Camera RAW and version 8.3 now supports the Nikon Df RAW files. If you have a previous version of Photoshop CS5 and earlier you will not be able to use Camera RAW 8.3, but you can use the Adobe DNG converter (see below) and then open the converted .DNG file.
Adobe DNG Converter – Adobe’s Digital Negative Gallery (DNG) format can be opened by a variety of programs. Using this converter, you can convert your Nikon Df .NEF files to Adobe .DNG format, and then open your RAW images in programs that do not support Nikon Df files directly. The Adobe DNG Converter version 8.3 adds Nikon Df support. Download for Windows and Macintosh.
Nikon Transfer – Not recommended! If you have trouble opening the Nikon Df .NEF files using the latest versions the programs that are supposed to have Nikon Df support, you may have used an old version of Nikon Transfer program to copy images from your camera. It is known to corrupt .NEF files and can cause problems opening them. If you have corrupted .NEF files you may be able to use this repair program to fix them.
ExifTool – Using this program you can change EXIF data stored in the RAW fils. Because the Nikon Df shares the same sensor as the Nikon D4, you can modify the camera model to the D4 in the RAW image files. Then if a program supports the D4 it will be able to open the Nikon Df .NEF file. Download ExifTool. First install the ExifTool and then use the command line:
exiftool.exe -model="NIKON D4" *.NEF
