Auto-bracketing
The
auto-bracketing function
allows you
to make a
series
of increased
and
decreased
exposures
in rapid
succes-
where
the background is
very light while
a much smaller
but important
part of the image is
comparatively much
darker.
The opposite
situation
can also be
corrected
where,
for
example,
a
light
coloured object is positioned
in front
of
a very dark
background. In
this case an averaged TTL
meter
reading
will suggest a reading
that would pro-
duce an overexposed
image. A
decrease
compensation
of
-1.5,
for
example, can
be applied
producing
a back-
ground
tone that was closer
to the original
and dark-
ening
the object to
a
more'natural'tone.
Similar situ-
ations might
be an object
placed in
sunlight against
a
background
in
shadow,
for example.
The
amount
of compensation required
will differ
from
case to case
dependant on the situation
and
the desired
effect.
Do not forget
to
re-set
the exrysure
compensation
dial bock to zero
after use.
Check regularly
thatthe
exposure compenntion
dial
has
not
been unintentionally
changed.
sion to ensure an
optimal exposure without having to
al-
ter the
settings
after each
exposure. This
is
particularly
useful when
using
reversal
film that inherently has little
tolerance
for
exposure error. It
under- and
overexposes
(by
altering the
shutter
speed)
using the chosen exposure
setting as standard providing
three separate exposures.
Half
or
full EV
step variations can be made. Proceed
as
follows:
l. Set the film transport mode
to'S'or'C'.
2.Depress
the
'AEB'
button located
below the M/ d
panel.
The'AEB'
symbol
will appear
in
the square
in the M/d
(fig.35).'t
0.5'will
also appear,
replaced
by
'*
f if
depressed one more
time and
finally
a
return
to neutral if pressed for
a third
time.These
figures show
the amount
of exposure variation you
can
choose from
for the
three
frame
sequence.
3.
Determine
the exposure
as normal in manual
or'au-
tomatic'mode.
4. Press
the
shutter release
button
(or
remote release)
and keep it pressed
until the three frames have
been
exposed.
The
exposures will consecutivelybe
: standard, under,
over.
They
are also indicated
in the M/d as follows

0.5 EV is your
choice ofvariation for this
example) :
