Option Description
TIFF-RGB
Images are saved in uncompressed TIFF RGB at a color depth of eight
bits per channel (24-bit color).
JPEG Fine
Images are saved in JPEG format at a compression ratio of roughly
1 :4.
JPEG Normal
Images are saved in JPEG format at a compression ratio of roughly
1:8.
JPEG Basic
Images are saved in JPEG format at a compression ratio of roughly
1 :16.
NEF (Raw)
Raw 12-bit data from the CCD are saved directly to the memory
card in Nikon Electronic Image Format (NEF). NEF files can only be
viewed in Nikon View 5 or Nikon Capture 3 ( 169). Two NEF
modes are available:
NEF (Raw)
In this mode, NEF images are not compressed, reducing the time
needed to process images before they are saved to the memory
card but increasing file size.
Comp. NEF (Raw)
In this mode, NEF images are compressed using a virtually “loss-
less” algorithm that reduces file size by approximately fifty to sixty
percent without affecting image quality. More time is required to
process images before they are saved to the memory card ( 43).
