Close up: Your D70 makes some
adjustments suitable for close-up
photos when you choose this
mode. For example, the automatic
focusing mechanism will concen-
trate on the center of the frame
(because that's where most close-
up subjects are located), and not
seek sharp focus until you partially
depress the shutter-release button.
Sports: The D70 switches into a
continuous autofocus mode that
tries to track moving subjects to
keep them in focus. It also uses
higher shutter speeds and turns
the flash off. Because the D70 fig-
ures you don't want to miss a fast-
moving shot, the shutter will trip
even if focus hasn't been achieved.
Night landscape: In this mode,
the D70 uses shutter speeds as
long as 17 seconds to allow dark
backgrounds and shadows to be
properly exposed. The flash is
turned off.
Night portrait: Similar to night
landscape mode, this mode adds
flash capability and tries to balance
flash exposure with the back-
ground illumination using front-
curtain slow synchronization.
Semiautomatic and
Manual Exposure
Modes
The Nikon D70 has three semiautomatic
exposure modes that allow you to specify
shutter speed, aperture, or combinations
of the two; and a manual exposure mode
that gives you the complete freedom to set

shutter speed and aperture. These four
exposure modes are also set using the
mode dial. Your choices include:
Program: In this mode, the D70
automatically chooses an appropri-
ate shutter speed and f-stop to
provide the correct exposure.
However, you can override these
settings in several ways. In all
cases, if your attempted adjust-
ments result in an exposure
beyond the range of the system
(that is, you're asking for a shutter
speed or f-stop that's not avail-
able), either HI or LO will appear in
the viewfinder.
Rotate the main command dial
•
to the left to change to a slower
shutter speed and smaller f-stop
combination that provides the
same overall exposure.
Rotate the main command
•
dial to the right to change to
a higher shutter speed and
larger f-stop combination that
provides the same overall
exposure.
Hold down the EV button and
•
rotate the main command dial
to the left or right to add or
subtract exposure from the
metered exposure reading.
Shutter priority: In this exposure
mode, you specify the shutter
speed with the main command
dial, and the D70 will select an
appropriate f-stop. The HI and LO
warnings will appear if you exceed
the range of available settings.
Aperture-priority: In this expo-
sure mode, you specify the f-stop
to be used with the sub-command
