# Adjusting the white balance

The white balance must be adjusted again when the lighting conditions change. Follow the steps below to adjust the white balance automatically.

#### When storing in <A> of the <WHITE BAL> switch

Switch to manual mode with the <AUTO/MANUAL> switch. (Shooting)

Set the <GAIN> switch.

Normally, set this to 0 dB. If it is too dark, set the gain to an appropriate value.

Set the <WHITE BAL> switch to <A>.

Change the <ND FILTER> switch settings according to the light conditions.

For setting examples for the <ND FILTER> switch, refer to “Brightness adjustment”.

Place the white pattern at a point where the light conditions match those for the light source for the subject, and zoom in on the white pattern so that the white color appears in the screen.

Adjust the lens aperture.

Adjust the iris so that the brightness of Y GET is approx. 70%.

Press the <AWB> button.

White balance is automatically adjusted.

#### White pattern

- A white object (cloth or wall) near the subject may also be used for the white pattern.

- Required size of white pattern is as follows.

  1/2 or more of the screen width

  1/2 or more of the screen height

- Keep bright spotlights out of the screen.

- The white pattern must be placed at the center of the screen.

#### Messages displayed in the viewfinder and LCD monitor

- When the auto tracking white balance (ATW) function is operating, white balance cannot be adjusted.

Status | Message | Remark

During adjustment | [AWB Ach ACTIVE] |
Adjustment completed | [AWB A OK 3200K] | The adjusted value is automatically stored in the specified memory (A or B).
When the color temperature of the subject is lower than 2000 K or higher than 15000 K | [AWB NG COLOR TEMP LOW] [AWB NG COLOR TEMP HIGH] | [AWB NG COLOR TEMP LOW] indicates that the temperature is lower than the displayed temperature. [AWB NG COLOR TEMP HIGH] indicates that the temperature is higher than the displayed temperature.

#### [COLOR TEMP Ach SETTING]/[COLOR TEMP Bch SETTING] setting

- The color hue can be changed after the white balance has been adjusted automatically, after setting each item in the main menu → [SCENE FILE] → [COLOR TEMP Ach SETTING]/[COLOR TEMP Bch SETTING].

- Adjusting either one of [COLOR TEMP], [R Gain], [B Gain], and [G AXIS] changes the other three values.

- Applying white balance automatic adjustment again resets [COLOR TEMP], [R Gain], [B Gain], and [G AXIS].

## When you have no time to adjust the white balance

Set the <WHITE BAL> switch to <PRST>.

- Each time the <AWB> button is pressed, the values set in [3200K], [5600K], and main menu → [SW MODE] → [W.BAL VAR] are toggled in order.

When [VAR] is selected, turning the <SEL/PUSH SET> dial button can set any white balance value between [2000K] and [15000K].

- The value displayed as [VAR] is not always assured. Use it as a reference value.

- The value for [VAR] can be viewed by pressing the <AWB> button.

## When the white balance has not been automatically adjusted

When the white balance has not been successfully adjusted, an error message is displayed on the viewfinder screen and LCD monitor displays.

Error message | Meaning | Remedy

[AWB Ach NG] or [AWB Bch NG] | The color temperature is too high, or too low. | Select the appropriate filter.
[LOW LIGHT] | There is insufficient light. | Increase the amount of light or increase gain.
[LEVEL OVER] | There is too much light. | Decrease the amount of light or decrease gain.
[COLOR TEMP LOW] or [COLOR TEMP HIGH] | The color temperature is too high, or too low. | Select the appropriate filter or light source.

## Manual setting of color temperature

The color temperature of white balance can be adjusted by the setting menu.

Press the <AWB> button to select [W.BAL VAR] mode.

Set the color temperature in the main menu → [SW MODE] → [W.BAL VAR].

This can be set from [2000K] to [15000K].

NOTE

- It can also be operated by the <SEL/PUSH SET> dial button. For details, refer to “Direct menu operation”.

## Viewfinder and LCD monitor screen displays relating to white balance

For details, refer to “Screen status display”.

## Setting the auto tracking white balance (ATW) function

The camera is equipped with the Auto Tracking White Balance (ATW) function that automatically tracks the white balance of images according to the lighting conditions.

The auto tracking white balance function can be assigned to each of <A>, <B>, and <PRST> of the <WHITE BAL> switch. Configure the settings in the main menu → [SW MODE] → [ATW].

Note that if the auto tracking white balance function is assigned to the USER button, the function follows the operation of the USER button.

For details, refer to “Assigning functions to the USER buttons”.

## Canceling the auto tracking white balance

Press the USER button to which auto tracking white balance function is assigned again or change the position of the <WHITE BAL> switch. Note that if the auto tracking white balance function is set to the <WHITE BAL> switch, the function cannot be canceled with the USER button.

NOTE

- This function does not guarantee 100% accuracy for the white balance. Note that the tracking performance relative to changes in ambient lighting and white balance performance has been given a certain degree of latitude.

- Auto tracking white balance does not function when the frame rate is set to [9fps] or lower in variable frame rate, and when the shutter speed is set to less than 1/12.
