NEF (RAW) Recording
The [NEF (RAW) recording] item in the shooting menu controls
compression (pg. 68) and bit depth (pg. 68) for NEF (RAW) images.

JPEG Compression
JPEG images can be compressed for relatively uniform file size or optimal
image quality. The [JPEG compression] option in the shooting menu can
be used to choose the type of compression (pg. 67).
A
NEF (RAW)+JPEG
If only one memory card is used, only the JPEG image will be displayed
when photographs taken at [NEF (RAW) + JPEG fine], [NEF (RAW) + JPEG
normal], or [NEF (RAW) + JPEG basic] are viewed on the camera. Deleting
the JPEG image deletes the NEF (RAW) copy. If two memory cards are
inserted and [RAW Slot 1-JPEG Slot 2] is selected for Slot 2, deleting the
JPEG copy from the memory card in slot 2 has no effect on the NEF (RAW)
copy on the memory card in slot 1 (pg. 71).

The Image Quality Menu
Image quality can also be adjusted using the [Image quality] option in the
shooting menu (pg. 290).
