Pentax digital spotmeter - Exposure Techniques for Special Effects

The
light
level
read
at
the
highlights
is
set
on the
exposure
calculator
by index
10 of
the IRE
Scale.
With
color
f ilm, only
those
shadows
with
a
light
level
reading
falling to the
right of
index 1
of the
IRE
scale
(black
level)
will be
reproduced.
Areas
with
a
light
value
falling
below
index
1
will
appear
as
unrelieved
shadow.
Therefore,
when
the
light
level of
the
highlights
has been set
on index
10,
if
important
shadow
detail
has
insuff icient
light to
bring
it
above
index
1, it
will have
to be
given
additional
illumination
until its
light level
reading does
exceed
this
mark.
EXPOSURE
FOR
SPECIAL
EFFECTS
Highlight
metering
is also
a
convenient
means
of
achieving
an
underexposed,
low-key
effect
which
is desirable
when creating
a
nocturnal
atmosphere
i n
a
da
yti
me
shot.
To achieve
this
effect,
read
the light
level of
the
highlights,
and
set
this
number
on the
exposure
calcu
lator by
one of the
lR
E
indexes
chosen
in
accordance
with the degree
of density
desired
in
the
resu
lti
ng
photograph.
For example,
if
the
light
level of
the
highlights
is
EV
16,
and
this
value is set
on
the
exposure
calculator
by
the
standard
index, the
highlights
will be
reproduced
in
a
gray
tone
as
if
they
were
a
standard
18%
ref lective
surface.
