NEF (RAW) Bit Depth
Option Description
N
[ Lossless
compressed ]
NEF pictures are compressed using a reversible
algorithm. The resulting files are about 60% to
80% the size of pictures recorded using
[
Uncompressed ]. Image quality is the same as
pictures recorded using [ Uncompressed ].
O [ Compressed ]
NEF images are compressed using a non-
reversible algorithm. The resulting files are about
45% to 65% the size of pictures recorded using
[
Uncompressed ]. Image quality is nearly the
same as pictures recorded using
[
Uncompressed ].
[ Uncompressed ]
NEF pictures are not compressed; the resulting
files are larger than those for pictures recorded
using [
Lossless compressed ] or [ Compressed ].
Option Description
q
[ 12-bit ]
NEF (RAW) images are recorded at a bit depth of
12 bits.
r
[ 14-bit ]
NEF (RAW) images are recorded at a bit depth of
14 bits. Files recorded at a bit depth of 14 bits
contain more color data than pictures recorded
using [
12-bit ]. Files recorded at a bit depth of
14 bits are also larger than pictures recorded
using [
12-bit ].
