The following options can be accessed from the shooting menu. Press the G button to display the menus, highlight the desired option and press 2.

❚❚JPEG Compression

Choose the type of compression for JPEG images.

Option Description

OSize priority Images are compressed to produce relatively uniform file size.

POptimal quality Optimal image quality. File size varies with scene recorded.

❚❚NEF (RAW) Recording > Type

Choose the type of compression for NEF (RAW) images.

Option	Description
Lossless	NEF images are compressed using a reversible algorithm, reducing
N compressed	file size by about 20–40% with no effect on image quality.
	NEF images are compressed using a non-reversible algorithm,

OCompressed reducing file size by about 35–55% with almost no effect on image quality.

❚❚NEF (RAW) Recording > NEF (RAW) Bit Depth

Choose a bit depth for NEF (RAW) images.

	Option	Description
d	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, producing
		files larger than those with a bit depth of 12 bits but increasing the
		color data recorded.

ANEF (RAW) Images

NEF (RAW) images can be viewed on the camera or using software such as Capture NX 2 (available separately; 0 298) or ViewNX 2 (available on the supplied ViewNX 2 CD). Note that the option selected for image size does not affect the size of NEF (RAW) images; when viewed on a computer, NEF (RAW) images have the dimensions given for large (#-size) images in the table on page 95. JPEG copies of NEF (RAW) images can be created using the NEF (RAW) processing option in the retouch menu (0 271).

ANEF+JPEG

When photographs taken at settings of NEF (RAW) + JPEG are viewed on the camera with only one memory card inserted, only the JPEG image will be displayed. If both copies are recorded to the same memory card, both copies will be erased when the photo is deleted. If the JPEG copy is recorded to a separate memory card using the Role played by card in Slot 2 > RAW Slot 1—JPEG Slot 2 option, deleting the JPEG copy will not delete the NEF (RAW) image.
