PREPARATIONS FOR OPERATION

White Balance Adjustment

Since the color of light (color temperature) varies depending on the light source, it is necessary to re-adjust the white balance when the main light source illuminating the subject changes.

•ERROR: LOW LIGHT (Insufficient illumination)

Displayed when the illumination is dim. Increase the illumi- nation and then re-adjust the white balance.

•ERROR: OVER LIGHT (Excessive illumination) Displayed when the light is excessively bright. Decrease the illumination and then re-adjust the white balance.

White Balance Adjustment

Two kinds of white balance adjustment results can be stored in memories AUTO A and AUTO B.

Adjustment procedure

1. Set the following switches.

• Set the POWER switch to ON.

• Set the IRIS mode switch of the lens to A (Auto).

• Set the FULL AUTO switch to OFF.

2. Set the ND filter switch according to the current lighting.

3. Set the WHT.BAL switch to A or B.

4. Place a white object near the center of the screen under

the same lighting conditions as the target subject and

zoom in to fill the screen with white.

5. Press the AWB (Auto White Balance) button.

“AUTO WHITE A, B OPERATION” is displayed in the view-

finder while the auto white balance adjustment circuit operates.

When correct white balance is obtained, the approximate

color temperature is displayed together with “AUTO

WHITE A, B OK” for about 5 seconds.

Error messages

If the adjustment ends abnormally, an error message, as described below, blinks for about 5 seconds.

•NG: OBJECT (Improper object)

Displayed when there is not enough white color on an object or the color temperature is not suitable.

Replace the color temperature conversion filter or use another white object and re-adjust the white balance.

•Do not adjust using any highly reflective objects, such as metal, etc., as this may result in improper white balance adjustment.

•The FAW (Full Auto White balance) function cannot pro- vide optimum white balance with a subject outside the FAW adjustment range, for example when it contains only a single color or not enough white color.

•The accuracy of the FAW (Full Auto White balance) is inferior to that of the Auto white balance.

•When the power is turned on with the FAW mode selected, it takes about 10 seconds for the FAW adjust- ment to be completed.

Do not shoot within this interval.

Full Auto White Balance (FAW)

The FAW function adjusts the white balance value automati- cally as the lighting condition changes.

This mode is convenient when you have no time to adjust the white balance or when the camera is moved frequently in and out of places under different lighting conditions.

„Setting procedure

The FAW function can be activated with the FAW item on the SWITCH MODE menu screen. The FAW function can be allocated to one of the white balance switching switches A, B, or PRESET.
