The JPEG compression menu offers the following options for JPEG images:

(RAW) + JPEG fi ne, NEF (RAW) + JPEG nor-

JPEG normal, or JPEG basic.
The effects of these options are most pronounced with large image sizes
(

RAW+BASIC or BASIC, or heavy sharpening ( 68). To choose an option:
1 Highlight JPEG compression in the shooting
menu ( 168) and press the multi selector to
the right.
File Names
Photographs are stored as image fi les with names of the form “DSC_nnnn.xxx,”
where nnnn is a four-digit number between 0001 and 9999 as signed automatically
in ascending order by the camera, and xxx is one of the following three letter exten-
sions: “NEF” for NEF images, “TIF” for TIFF-RGB, “JPG” for JPEG im ag es, and “NDF”
for Dust Off ref photos (
221–222). The NEF and JPEG fi les recorded at a setting of
“NEF+JPEG” have the same fi le names but different extensions. Images recorded at a
Color space setting of Adobe RGB (
70) have names that begin with an underbar
(e.g., “_DSC0001.JPG”). The “DSC” portion of the fi le name can be changed using
the File naming option in the shooting menu (
173).
