A NEF (RAW)
• NEF (RAW) files have the extension “*.nef”.
• The process of converting NEF (RAW) pictures to other highly-portable
formats such as JPEG is referred to as “NEF (RAW) processing”. During this
process, Picture Controls and settings such as exposure compensation and
white balance can be freely adjusted.
• The RAW data themselves are unaffected by NEF (RAW) processing and
their quality will remain intact even if the pictures are processed multiple
times at different settings.
• NEF (RAW) processing can be performed using [ Retouch ] > [ RAW
processing (current picture) ] or [ RAW processing (multiple pictures) ] in
the playback i menu or on a computer using Nikon’s NX Studio software.
NX Studio is available free-of-charge from the Nikon Download Center.
A “NEF (RAW) + JPEG”
If [ RAW Slot 1 - JPEG Slot 2 ] is selected for [ Role played by card in Slot 2 ],
the NEF (RAW) copies will be recorded to the card in Slot 1 and the JPEG
copies to the card in Slot 2 (
0 503).
