Technical Notes
Image File and Folder Names
In the internal memory or on the memory card, pictures are identified by file names
with three parts: a four-letter identifier, a four-digit file number assigned automatically
by the camera in ascending order, and a three-letter extension (e.g.,
“DSCN0001.JPG”). When a picture is viewed on the monitor, the file number and ex-
tension appear in the top right corner of the display. The identifier is not displayed, but
is visible when images are transferred to a computer.
• Pictures are stored in a folder created automatically by the camera. The folder name
includes a three-digit folder number (e.g., 100NIKON). Folders can hold up to 200
pictures; if a picture is taken when the current folder contains 200 pictures, a new
folder will be created by adding one to the largest folder number (e.g., 100NIKON
J 101NIKON).
• When taking pictures using F PANORAMA ASSIST (P.40), Ultra HS (P.80), or In-
tvl timer shooting (P.80), each sequence of pictures is stored in a folder with a
name consisting of a three-digit folder number followed by “XXXP_xxx”,
“XXXN_xxx”, or “XXXINTVL” (e.g., “101P_001”, “101N_001” or “101INTVL”).
• If you take a picture when the current folder contains a picture numbered 9999, a
new folder will be created and file numbering will begin again from 0001.
• If file number reaches 200 or picture number reaches 9999 when the internal mem-
ory or the memory card contains a folder numbered 999, no further pictures can be
taken, even if there is still memory capacity. Replace the memory card, or transfer all
pictures to a computer (P.62), and after formatting the internal memory or the mem-
ory card (P.106), perform Reset all (P.108).
Getting Good Results with Autofocus
Autofocus performs best when there is contrast between the subject and the back-
ground and the subject is evenly lit. It does not perform well if the subject is very dark
or moving rapidly, if there are objects of sharply differing brightness in the scene (e.g.,
the sun is behind your subject and their features are in deep shadow), or if there are
several objects at different distances from the camera at the center of the frame (e.g.,
your subject is inside a cage).
