Nikon D2H Manuel D’Utilisation

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

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

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

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

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

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

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

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

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

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

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.
