Adjusting the Black Balance and the White Balance

Chapter 3 Adjustments and Settings

Note

If the camcorder has a zoom lens with an automatic

iris, the iris may hunt

during the adjustment. To

prevent this, adjust the iris gain knob (indicated as

IG, IS, or S) on the lens.

For details, refer to the lens operation manual.

1) Hunting: Repeated brightening and darkening of

the image, resulting from repeated response to

automatic iris control.

If the automatic white balance adjustment

cannot be made

If any of the above error messages is displayed,

retry the white balance adjustment. If the error

message occurs again, an internal check is

necessary.

For information about this internal check, contact

your vendor or a Sony service representative.

If you have no time to adjust the white

balance

Set the WHITE BAL switch to PRST.

This makes it possible to automatically set the

white balance to 5600K (factory default value) by

pressing the COLOR TEMP. button.

The color temperature to which the white balance

is set when the COLOR TEMP. button is pressed

can be selected from among 3200K, 4300K,

5600K, and 6300K on OPERATION

>Assignable SW in the setup menu. You can also

assign color temperatures to the ASSIGN. 1/3

switches or ASSIGNABLE 4/5 switches.

To change the color temperature when

the ND filter is switched

You can assign electrical CC (color correction)

filters to ND filters (see page 13). This allows you

to change the color temperature automatically

when the ND filter is switched.

1 Set “MAINTENANCE” > “White

Filter” > “ND Filter C.Temp” in the

setup menu (see page 137) to “On.”

2 To assign an electrical CC filter to

FILTER selector position number 1,

select “ND FLT C.Temp<1>.” To assign

it to positions 2 to 4, select “ND FLT

C.Temp<2-4>.”

3 Turn the MENU knob to select the

desired color temperature.

As you turn the MENU knob, the color

temperature changes as follows: 3200K y

4300K y 5600K y 6300K.

4 Repeat steps 2 and 3 as required.

To switch between electrical CC filters

with an assignable switch

You can assign the function that switches

between electrical CC filters to an assignable

switch. This allows you to switch between color

temperatures (3200K/4300K/5600K/6300K) that

have been assigned to up to four positions (A to

D) with each press of the assignable switch.

Regardless of assignments to assignable

switches, you can also switch between the color

temperatures assigned to each position from a

RM-B170/B750 Remote Control Unit.

1 Select “MAINTENANCE” > “White

Filter” in the setup menu (see page 137).

2 Select the position to which to assign a

CC filter by selecting one of “Electrical

CC<A>” to “Electrical CC <D>,” and

then turn the MENU knob to select the

desired color temperature.

As you turn the MENU knob, the color

temperature changes as follows: 3200K y

4300K y 5600K y 6300K.
