Joint
@
The
joint connects the arm to the speedlight and allows
the flash head to
be
positioned
as
required for various
shooting situations.
The
arm can be inserted from either side of the joint,
the normal position
is
shown
in
the photo. When using
two
SB-102
Speedlights and the optional Double Flash
Bracket, insert the arm that
is
next to the camera's film
advance lever into the joint from the direction opposite
that shown
in
the photo. (Flash head positioning scales
are provided
on
both sides of the joint.)
The
joint lever allows the flash head to
be
turned
on
the
arm's axis and moved
up
or down the arm as required.
The
joint knob
is
used to adjust the angle of the flash
head (the angle of intersection between the speedlight's
axis and the lens's optical axis): The normal angle of the
flash head
is
with the flash head positioning index @ at
the

Close-Up
Shooting
in
the
Non-TTL
Automatic Mode
When using the
SB
-
102
in
the non-TTL automatic mode
for close-up shooting within approximately 1 m (3.3ft) to
0.
3m
(1
ft), the flash head should
be
pointed directly at
the subject. Exposure compensation will
be
necessary,
though, to prevent the subject from being overexposed.
As
a rule of thumb, choose
an
aperture 1/2 to 1 step
smaller (numerically larger f-numbers) than indicated
by
the exposure calculation dial.
Of
course, the exact
amount of exposure compensation depends upon the
shooting situation,
so
additional compensation may
be
required.
To
determine the exact amount of exposure compensa-
tion required before going to the actual shooting loca-
tion, test-shoot
in
a location with conditions similar
to
those of the actual situation (similar water quality, sur-
roundings, subjects, and so on). If the conditions
change, the amount of the exposure compensation will
need to
be
changed correspondingly. Naturally, data
calculated
on
land will not be applicable to underwater
photog raphy.

tioning scale. The "normal" position
is
used for shooting
between 1 m (3.3ft) and infinity. For close-up shooting
within approximately 1 m (3.3ft), loosen the joint knob,
point the flash head toward the subject, then tighten the
joint knob.
In
addition to the
"normal"
position mark
on
the flash head positioning scale,
"0.6m
(2ft)" and "0.
3m
(1ft)" position marks ® ® are provided for use when
shooting subjects at these distances. However, when
the flash head
is
not
in
the "normal" position, the joint
must
be
attached to the top of the arm.
For information about using the target-light to position
the flash head, see page
29.
To
detach the jOint from the speedlight, turn the joint
knob counterclockwise and slide the
jOint
plate out of
the joint collar while pulling the joint knob.
