dramatically.

Use
this
function
for
shooting

so
dark
places
that
fully
opening
the
lens
iris
can
still
not
give
an
acceptably
bright
image.
The

can
be
set
in
the

of
0
to
18
dB

Changing
Camera
Settings
for
Better
Picture
CCD
IRIS
ON:
When
an
excessive
amount
of
light
passes
through
the
lens,
this
function
increases
the
shutter
speed
automatically
to
nearly
the
same
effect
that
the
lens
iris
is
narrowed
3
stops
down.
In
microscope
shootings
using
a
microscope
adaptor
without
incident
light
control
capability,
for
example,
an
amount
of
incident
light
which
is
not too
much
for
a
human
eye
will
often
be
so
for
a
video
camera.
With
CCD
IRIS
set
to
ON,
an
excessive
amount
of
incident
light
is
automatically
decreased
to
an
appropriate
level
for
the
video
camera.
In
another
example,
if
there
is
a
very
bright
object
(such
as
snow,
or
sea
water
reflecting
sunlight)
within
the
range
of
view
of
the
lens,
the
incident
light
is
automatically
decreased
to
a
certain
level
if
of
course
the
lens
has
an
automatical
iris
control
capability.
Also
in
such
case,
CCD
IRIS
is
useful
to
give
a
further
decrease
of
incident
light.
OFF:
for
shooting
in
normal
lighting
condition.
Also
use
this
setting
when:
©
The
picture
flickers
on
the
monitor
screen.
This
may
occur
when
using
the
DXC-930
with
lighting
power
of
$0
Hzor
the
DXC-930P,
of
60
Hz.
In
such
case,
set
CCD
IRIS
to
OFF
and
shutter
speed
to
FL.
(See
the
next
page.)
©
The
camera
is
used
under
fluorescent
light.
This
may
cause
slow
variations
in
color
to
the
picture.
If
the
degree
of
color
variations
is
unacceptable,
set
CCD
IRIS
to
OFF.
