Taking Photographs—Image Quality and Size

Image Quality and Size

Making Effective Use of Memory

Together, image quality and size determine how much space each pho to -
graph occupies on the memory card.

Image Quality

The D2Xs supports the following image quality options (listed in descending
order by image quality and fi le size):

Option

Description

NEF (RAW) +

JPEG fi ne

Two images are recorded, one NEF (RAW) image and one fi ne-qual-
ity JPEG image.

NEF (RAW) +

JPEG basic

Two images are recorded, one NEF (RAW) image and one basic-qual-
ity JPEG image.

NEF (RAW) +

JPEG normal

Two images are recorded, one NEF (RAW) image and one normal-
quality JPEG image.

NEF (RAW)

Raw 12-bit data from the image sensor are saved directly to the
memory card in Nikon Electronic Format (NEF).

TIFF (RGB)

Record uncompressed TIFF-RGB images at a bit depth of 8 bits per
channel (24-bit color). Time needed to record images increases.

JPEG normal Record JPEG images at a compression ratio of roughly 1 : 8.

JPEG fi ne

Record JPEG images at a compression ratio of roughly 1 : 4.

JPEG basic

Record JPEG images at a compression ratio of roughly 1 : 16.

NEF (RAW) / NEF + JPEG

NEF (RAW) images can only be viewed using compatible software such as PictureProject
or Capture NX (

250). When photographs taken at NEF (RAW) + JPEG fi ne, NEF

(RAW) + JPEG normal, or NEF (RAW) + JPEG basic are viewed on the camera, only
the JPEG image will be displayed. When photographs taken at these settings are de-
leted, both NEF and JPEG images will be deleted.

White balance bracketing can not be used with NEF (RAW) images. Se lect ing an NEF
(RAW) option for image quality cancels white balance bracketing.

TIFF (RGB)

About 30 s are required to record a TIFF (RGB) image (1 GB SanDisk SDCFX (Extreme III)
card; recording time varies with make of memory card).
