111USING BUILT-INFLASH RED-EYE REDUCTION FLASH FUNCTION This camera includes a red-eye reduction flash function, which reduces the red-eye phenomenon utilizing pre-flash. In this mode, the pre-flash is discharged just before the shutter is released which reduces the diameter of the pupil of the eye. Then the main flash is discharged while the pupils are smaller, which in turn reduces the red-eye effect. ABOUT RED-EYE PHENOMENON Shooting portraits with flash in a dark environment often causes a subject eyes to turn out reddish in the print. This phenomenon, commonly known as "Red-Eye", is caused by the reflection of the electronic flash in the retina of your subject eye. It can be reduced by taking a picture in a brighter light condition or by shooting with a wider-angle lens at a closer distance, or by employing the red-eye reduction flash feature. When using a Pentax dedicated flash unit off the camera, it may also help to position the flash as far away from the camera as possible. FLASH EFFECTIVE RANGE FOR THE PICTURE MODE As a rule of thumb the distance for using the built-in flash (which varies with the lens used) is within about four meters (using ISO 400 film). 4 • TilfehstMheseEftlhlaMeasnOnhs0ea.fp7femecrtti(uv2re.e6rfiats)n,sgtoheesdmcooearslrl.enWcothteecxonpmoasesucurlebojseceacrnt tinshoastnhbo0et.7oambt taa(i2dn.ie6sdftta,)n,acenevden • you will see vignetting in the picture corners.

REDUCTION
FLASH
FUNCTION
This
camera
includes
a
red

reduction
flash
function,
which
reduces
the
red
-eye
phenomenon
utilizing
pre
-flash.
In
this
mode,
the
pre
-flash
is
discharged
just
before
the
shutter
is
released
which
reduces
the
diameter
of
the
pupil
of
the
eye.
Then
the

is
discharged
while
the
pupils
are
smaller,
which
in
turn
reduces
the

effect.
ABOUT
RED
-EYE
PHENOMENON
Shooting
portraits
with
flash
in
a
dark
environment
often
causes
a
subject
eyes
to
turn
out
reddish
in
the
print.
This
phenomenon,
commonly
known
as
"Red
-Eye",
is
caused
by
the reflection
of
the
electronic
flash
in
the
retina
of
your
subject
eye.
It
can
be
reduced
by
taking
a
picture
in
a
brighter
light
condition
or
by
shooting
with
a
wider
-angle
lens
at
a
closer
distance,
or
by
employing
the
red
-eye
reduction
flash
feature.
When
using
a
Pentax
dedicated
flash
unit
off
the
camera,
it
may
also
help
to
position
the
flash
as
far
away
from
the
camera
as
possible.
FLASH
EFFECTIVE
RANGE
FOR
THE
PICTURE
MODE
As
a
rule
of
thumb
the
distance
for
using
the
built-in
flash
(which
varies
with
the lens
used)
is
within
about
four
meters
(using
ISO
400
film).

MEMO
•
The
flash
effective
range
does
not
come
closer
than
0.7m
(2.6ft),
even
if
the
lens
aperture
is
so
small.
When
a
subject
is
shot
at
a
distance
less
than
0.7m
(2.6ft),
the
correct
exposure
cannot
be
obtained,
and
you
will
see
vignetting
in
the
picture
corners.
•
Note
the
built-in
flash
pops
up
even
when
the
subject
is
far
away
or
beyond
the
maximum
flash
effective
range.
See
page

for
the
flash
effective
range.
