HOW Nikon PICTURE CONTROLS ARE APPLIED
If you shoot JPEGs it’s simple, but if you shoot RAW files the system is slightly different
Picture Controls are applied as the pictures you take are processed into image files. If you shoot JPEGs, this processing takes place inside the camera. If you shoot RAW (NEF) files, the processing is done later on using RAW conversion software on your computer. Nikon software can interpret and apply Picture Controls, but other RAW converters can’t and just ignore them.
