Choose a compression type and bit depth for NEF (RAW) photographs.

NEF (RAW) Compression

Option

Description

N

[Lossless compressed]

NEF images are compressed using a reversible algorithm. The resulting files are about 60% to 80% the size of uncompressed pictures.

O

[Compressed]

NEF images are compressed using a non-reversible algorithm. The resulting files are about 45% to 65% the size of uncompressed pictures.

NEF (RAW) Bit Depth

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].
