EXPOSURE MODE
light reaching
th
e
film
is
controlled
by the
shutter and aper-
ture. The
proper combination of shutter
and
aperture settings
results
in
the
correct
exposure. The necessary settings
will
be
based upon the ISO
speed set
for the film
in
use
and
the
operation
of the camera's exposure
control system.
The
relationship
between
aperture and shutter is as
follows:
One
change
in
shutter speed either doubles
or
halves
th
e
light
transmitted.
For
example, 1/500
passes half the
light
as
1/250
and
double
the
light
of 111000. The aperture
118
passes
half th
e
light
of
115.6
and
double
the
light of
1111.
If
the
correct
exposure
for
a scene
is 1/500 at
118,
then
we
can
also select
1/250
at
f/1
1
or
111000
at
115.6
and
achieve the same exposure results.
Selecting the exposure control mode
means
deciding
if
you
want
the shutter speed/aperture
to be
set
automatically
or
manually.
The Nikon N6000
offers five
modes:
four automatic exposure
control
modes -
Auto Multi-Program
(i:d),
Normal-Pro-
grammed (fj), Shutter-Priority auto
(~),
and
Aperture-Priority
auto (.BJ) -
in addition
to
Manual
(111)
mode.
Each
exposure
mode
has
its
own
advantages.
In Programmed
auto
exposure mode,
as the
optimum
combi-
nation of shutter speed
and aperture
is automatically
set
by
the
N6000's microcomputer, you
can
concentrate completely
on
picture
composition and
have greater
opportun
ities
to
shoot,
without worrying about exposure.

In Shutter-Priority auto
exposure
mode,
you can
manually
set
shutter speed as
desired. That
is, you can freeze
the
action
with
sharp,
clear
images
using
a fast shutter speed, or create
motion effects
by
choosing
slower
shutter
speeds.
In
Aperture-Priority
auto exposure mode, you
can control depth
of
field by
varying the aperture.
You
can
use
a
larger
aperture
(smaller
f-number) for
shallower
depth
of
field
to
create softer,
less
distinct
backgrounds, or choose a
smaller
aperture (larger
f-number)
for
greater depth
of
field.
In Manual
exposure
mode, in addition
to
controlling
both shut-
ter
speed and aperture,
you can
easi ly create intentionally
over-
or
underexposed
photos.
