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 D2H supports the following image quality options (listed in descending
order by image quality and fi le size):

Option

Description

NEF + JPEG

Fine

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

NEF + JPEG

Basic

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

NEF + JPEG

Normal

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

NEF (Raw)

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

TIFF (RGB)

Images are saved in uncompressed TIFF-RGB at a color depth of eight
bits per channel (24-bit color).

JPEG

Normal

Images are saved in JPEG format at a compression ratio of roughly
1 : 8.

JPEG Fine

Images are saved in JPEG format at a compression ratio of roughly
1 : 4.

JPEG Basic

Images are saved in JPEG format at a compression ratio of roughly
1 : 16.

NEF (Raw) / NEF + JPEG

File compression for NEF images is controlled from the Raw compression menu (

44). The following options are available:
Comp. NEF (Raw): NEF images are compressed using a “loss less” algorithm that re-

duces fi le size by approximately fi fty to sixty per cent with out affecting image quality
(

46–47).

NEF (Raw): NEF images are not compressed.
NEF images can only be viewed in the software provided with the camera or in Nikon
Capture 4 (

223). When photographs taken at NEF + JPEG Fine, NEF + JPEG Nor-

mal, or NEF + JPEG Basic are viewed on the camera, only the JPEG image will be
displayed. When photographs taken at these settings are deleted, both NEF and JPEG
images will be deleted.
