Metering Modes; Iso Sensitivity; Setting White Balance - Nikon D70 Quicktour

Metering Modes

The D70 can use any of three different expo-
sure metering methods when set to any of
the semi-automatic or manual exposure
modes (which are discussed later in the
chapter). Select the metering mode by hold-
ing down the metering mode button and
spinning the main command dial until one
of these metering modes appears in the
monochrome LCD:
Matrix: The camera examines
1,005 pixels in the frame and
chooses the exposure based on
that information (plus, with Type G
and D lenses, distance range data).
Center-weighted: The camera col-
lects exposure information over the
entire frame,
but when
making its
calculations
emphasizes
the 8mm
center circle
(or other
size chosen
by you)
shown
in the
viewfinder.
Spot:
Exposure is
calculated
entirely from
an area
approximating
the currently
selected focus
area.

ISO 200 to ISO 1600.
ISO and white balance can
alternatively be set using the
menu system, which is dis-
cussed in Chapter 2. You can
also find more information on
ISO and white balance in
Chapter 3.
Setting White

to expose an image, you can set the white
balance. To use a preset value, follow these

1.
