NEF (RAW) Images
Note that the option selected for image size does not affect the size of NEF (RAW) or
NEF (RAW)+JPEG images. Date imprint (0 147) is not available at image quality settings of
NEF (RAW) or NEF (RAW)+JPEG.
NEF (RAW) images can be viewed on the camera or using software such as Capture NX 2
(available separately; 0 177) or ViewNX 2 (available on the supplied ViewNX 2 CD). JPEG
copies of NEF (RAW) images can be created using the NEF (RAW) processing option in the
retouch menu (0 160).
A
NEF (RAW) + JPEG Fine
When photographs taken at NEF (RAW) + JPEG fine 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.
A
File Names
Photographs are stored as image files with names of the form "DSC_nnnn.xxx, " where nnnn
is a four-digit number between 0001 and 9999 assigned automatically in ascending order by
the camera, and xxx is one of the following three letter extensions: "NEF" for NEF images,
"JPG" for JPEG images, or "MOV" for movies. The NEF and JPEG files recorded at a setting of
NEF (RAW) + JPEG fine have the same file names but different extensions. Small copies
created with the small picture option in the retouch menu have file names beginning with
"SSC_" and ending with the extension ".JPG" (e.g., "SSC_0001.JPG"); copies created with the
movie edit options (0 50) have file names beginning with "DSC_" and ending with the
extension ".MOV" (trimmed copies, e.g., "DSC_0001.MOV") or ".JPG" (JPEG stills); copies
created with the other options in the retouch menu have file names beginning with "CSC"
(e.g., "CSC_0001. JPG"). Images recorded with the Color space option in the shooting menu
set to Adobe RGB (0 133) have names that begin with an underscore (e.g.,
"_DSC0001.JPG").
