Mode
Selector
@l
The
shooting mode
se
lector
on
the back of the
SB-16
has
five click-stop settings. Directly above the selector (read-
ing
from left to right), there are the blue and orange dots
for non-TTL automatic operation, two white dots
in
the
middle indicating
MD
(Motor Drive) and M (Manual)
operation respectively, and a white square at the far right
which
is
for TTL operation.
As

as
the
SB-16
is
tu
rned
on
, one of the appropriate
LEOs
(green for TTL and red for
all
the rest) above the
se
le
ctor lights
up
to indicate the setting selected.
Usable shoot
ing
modes depending
on
the combination of
the type of the flash unit and camera are
as

TTL (through-the-Iens automatic operation)
This mode provides automatic through-the-Iens (TTL)
control of the flash exposure
at
any aperture from
fl2
to
fl22 to match the camera-to-subject distance: the farther
away the subject, the more light emitted
by
the flash
unit; the closer the subject, the less light given off.
Because the exposure
is
measured through the len
s,
no
exposure compensation
is
required
in
off-camera and/or
bounce-flash operation or even with a teleconverter or
filter attached to the lens.
This setting
is
also used for programmed TTL auto opera-
tion with F-501/N2020 and F-301/N2000.
A (non-TTL automatic operation)
In
the non-TTL automatic (A) mode, the light output of the
flash varies automatically to match the
fla
sh-to-subject
distance, but instead of the light being measured through
the lens,
it
is
read
by
the light sensor
on
the front of the
SB-16.
At
any film speed

tting, you have a choice of
two working apertures indicated
by
the blue A 1 and
orange
A2
aperture indicator lines
on
the bottom of the
exposure calculator dial.
