Manual
exposure
mode
Manual operation allows you to shoot at your choice
of
any combination of the
flstops
and eleven shutter
sp
eeds
on
the
camera's
dials. (Note that you
cannot
s
et
shutter speed between numbered settings.) By
varying these combinations, you can achieve not only
correct exposure but also such special
effects
as
under- or overexposure, blurred action, etc. Manual
is also valuable to develop your photographic instincts
and
skills, and
is
additionally
recommended
when an
electronic flash other than the Nikon dedicated flash
unit is used
How to select f/stop and shutter speeds
Exposure
is
determined
by the
co
mbination of the
sh
utt
er
speed and f/stop (aperture opening) As the
numbe
rs
on either the
flstop
or shutter speed dials
increase by one value, the
amount
of light entering
the film
is
reduced by approximately one half. For
example, the
amount
of light at 1/125 sec is about
one-half that at
1/60 sec., and the amount of light at
fl16
is
one-half that at fl11 . Brighter scenes require
either faster shutter speeds or smaller
aperture
openings (larger f I
number
s)
or
a
comb
in
ation of both
which will give the same
amount
of exposure; darker
scenes require the
re
verse For example, 1/250 sec.
at
f/8
is the
same
as either
11500
sec at
f15
.6 or
1/125 sec. at
f111
