Image Quality and Size

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
NEF + JPEG Two images are recorded, one NEF (RAW) image and one fi ne-quality
Fine JPEG image.
NEF + JPEG Two images are recorded, one NEF (RAW) image and one normal-qual-
Normal ity JPEG image.
NEF + JPEG Two images are recorded, one NEF (RAW) image and one basic-quality
Basic JPEG image.
Raw 12-bit data from the LBCAST image sensor are saved directly to
NEF (Raw)
the memory card in Nikon Electronic Image Format (NEF).
Images are saved in uncompressed TIFF-RGB at a color depth of eight
TIFF (RGB)
bits per channel (24-bit color).
Images are saved in JPEG format at a compression ratio of roughly
JPEG Fine
1 : 4.
JPEG Images are saved in JPEG format at a compression ratio of roughly
Normal 1 : 8.
Images are saved in JPEG format at a compression ratio of roughly
JPEG Basic
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.
