NEF — Nikon Electronic Format

Nikon's raw format across the DSLR and Z-mount lines. A NEF is a TIFF file with Nikon's data written into it — and because TIFF is a container general-purpose readers already parse, a NEF hands over its standard EXIF to an ordinary viewer. It also carries a full-size embedded JPEG preview, which is what your camera shows you on the back screen.

NRW — the Coolpix raw

The raw format from Nikon's Coolpix compacts. It is also TIFF-based, so it behaves much like a NEF in a general-purpose reader, though support in editing software is thinner simply because far fewer people shoot it.

Standard EXIF — read by everything

The fields the EXIF specification defines, which every manufacturer writes the same way:

• Make — NIKON CORPORATION, always in capitals, which is a quick brand fingerprint
• Model — NIKON Z 8
• LensModel — NIKKOR Z 24-70mm f/2.8 S
• FNumber, ExposureTime, ISOSpeedRatings, FocalLength
• Software — the firmware version, e.g. Ver.02.00
• Artist and Copyright— whatever you typed into the camera's copyright menu

The Nikon MakerNote — read by few

A proprietary block Nikon structures however it likes. The EXIF standard says nothing about its contents, so a tool can only read it if someone wrote a Nikon decoder for it:

• Picture Control — the colour and tone profile
• ActiveD-Lighting — shadow and highlight handling
• AFAreaMode, AFPoint — the focus point the camera used
• ShutterCount — total actuations on the body
• VRMode — whether Vibration Reduction was active
• HighISONoiseReduction, VignetteControl

Mac

macOS reads NEF natively. Open the file in Preview and choose Tools → Show Inspector, or select it in Finder and press Command-I, and you get the exposure basics: body, lens, aperture, shutter speed, ISO, and the date. Picture Control, Active D-Lighting, and the shutter count are not there and will not be.

Windows

Right-click the file, choose Properties, then the Details tab. You will see date, dimensions, and most of the standard camera fields. Windows needs Microsoft's Raw Image Extension installed before it will preview or read a NEF at all — and even then, the MakerNote stays closed.

Mobile

iOS and Android both show a basic info panel — date, size, sometimes the camera model — and nothing brand-specific. The quickest route on a phone is to open our EXIF viewer in the mobile browser: it reads the file on the device, with nothing uploaded and nothing to install.

Lightroom — reads the file, ignores the profile

Lightroom reads the standard EXIF happily: you can filter a catalogue by body, lens, ISO, or focal length. What it does not do is honour Nikon's rendering settings. Lightroom applies its own Adobe profile to a NEF and disregards the Picture Control and Active D-Lighting the camera asked for.

That is why a NEF can look punchy on the camera screen and flat the second it lands in Lightroom — the screen was showing you the embedded JPEG preview, rendered with your Picture Control; Lightroom is showing you the raw sensor data, rendered its own way. Adobe's Camera Matching profiles exist to approximate the Nikon looks, and they are the closest you get without leaving Lightroom.

NX Studio — reads everything, because it is Nikon's

If you are searching for Capture NX, the answer today is NX Studio: Nikon folded Capture NX-D and ViewNX-i into a single free application, and it is the one to download. It reads NEF and NRW completely, MakerNote included.

Because it is Nikon's own software, it shows the shooting information the way the camera meant it — Picture Control, Active D-Lighting, focus point, noise reduction, VR — and it will render your NEF exactly as the body did. It can also change those settings on a raw file after the fact, which no third-party converter can do faithfully.
