Please be sure to read all instructions thoroughly to get the most from your
camera.

transferring them to your computer.
Guide to Digital Photography
The Guide to Digital Photography (this manual) provides complete operating
instructions for your camera.
PictureProject Reference Manual (on CD)
The PictureProject Reference Manual contains information on using the
PictureProject software provided with your camera. For information on

CAUTION: Foreign Matter on the Low-Pass Filter
Nikon takes every possible precaution to prevent foreign matter from coming into
contact with the low-pass filter during production and shipping. The D70S, however,
is designed to be used with interchangeable lenses, and foreign matter may enter the
camera when lenses are removed or exchanged. Once inside the camera, this foreign
matter may adhere to the low-pass filter, where it may appear in photographs taken
under certain conditions. To prevent foreign matter from entering the camera, do not
exchange lenses in dusty environments. To protect the camera when no lens is in place,
be sure to replace the body cap provided with the camera, being careful to first remove
all dust and other foreign matter that may be adhering to the body cap.
Should foreign matter find its way onto the low-pass filter, clean the low-pass filter as
instructed on pages 194–195 of this manual, or have the low-pass filter cleaned by
authorized Nikon service personnel. Photographs affected by the presence of foreign
matter on the low-pass filter can be retouched using Nikon Capture 4 version 4.2 or
later (available separately) or the clean image options available in some third-party
imaging software.

Introduction—Getting to Know the Camera
The Viewfinder Display
Advanced Focusing Screen Display
When the background is bright, the active focus area ( 66) is highlighted in black.
When the background is dark, the active focus area is highlighted briefly in red as
needed to establish contrast with the background (“Vari-Brite” focus areas), making
it easier to identify the selected focus area. The viewfinder is also equipped with on-
demand grid lines. When On is selected for Custom Setting 8 (Grid display; 144),
a reference grid is superimposed over the display in the viewfinder. This grid is a useful
aid when composing landscape shots or when tilting or shifting a PC Nikkor lens.
Owing to the characteristics of this type of viewfinder display, you may notice fine lines
radiating outwards from the selected focus area, or that the display in the viewfinder
turns red when the selected focus area is highlighted. These phenomena are normal
and do not indicate a malfunction.

The Viewfinder Display
The focus-area and grid-line displays in the viewfinder (advanced focusing screen dis-
play) tend to brighten at high temperatures and to darken and exhibit slower response
times at low temperatures. The other displays in the viewfinder tend darken at high
temperatures and exhibit slower response times at low temperatures. All displays will
return to normal at room temperature.
No Battery
When the battery is totally exhausted or no battery is inserted, the display in the view-
finder will dim. This is normal and does not indicate a malfunction. The viewfinder
display will return to normal when a fully-charged battery is inserted.

Introduction—Getting to Know the Camera
The Mode Dial
In addition to Digital Vari-Programs that allow settings to be adjusted to suit
a particular scene simply by rotating the mode dial to the appropriate mode,
the D70S is equipped with exposure modes that offer complete control over
settings.
Digital Vari-Programs
Selecting a Digital Vari-Program automatically op-
timizes settings to suit the selected scene, making
creative photography as simple as rotating the mode
dial.
Freeze motion in sports shots.
Take close-ups of flowers, insects, or other small objects.
Shoot portraits with the background in soft focus.
Auto ( 32)
Use for “point-and-shoot” snapshots that leave the cam-
era in charge of settings. Recommended for first-time
users of digital SLR cameras.
Night Landscape ( 33)
Use when taking landscape shots at night.
Night Portrait ( 34)
Shoot portraits against a dimly-lit backdrop.
Landscape ( 32)
Preserve details in landscape shots.
