B: White balance adjustment
Normally the
WB
(white balance) switch is
set to the
A
(automatic) position and the
white balance is adjusted automatically. If a
manual white balance adjustment is
necessary, follow the steps below.
Set the
WB
switch to the
M
(manual)
position, then adjust the colour.
•
Turn
R
(VR403) to set the red ratio
and/or
B
(VR402) to set the blue ratio.
C: Electronic iris function setting
Use a manual iris lens and set the
EI/BLC
switch to the
EI
(electronic iris)
-ON
position, to engage the electronic iris
function.
Open the lens iris (shortest F stop setting).
The dynamic range of the electronic iris will
be as indicated in table

.
CAUTION:
•
The electronic iris is suitable for normal
indoor use. When the
EI/BLC
switch is
set to the
EI-ON
position, do not use an
auto-iris lens.
•
If used under fluorescent light, the
image may flicker. In such a case,
change to incandescent lighting or set
the
EI/BLC
switch to the
OFF
position
and use an auto-iris lens.
•
When shooting bright subjects, pay
attention to the light angle in order to
avoid or minimize the smear
phenomenon effect.
