The NEF is developed by LibRaw with AHD demosaicing, camera white balance, Nikon camera-matrix calibration when available, and 8-bit sRGB output.

Nikon NX Studio and raw editors can reopen the NEF with its capture controls; a PDF makes a fixed proof suitable for a review thread or report.
Useful info
