6. SETTING AND ADJUSTMENTS BEFORE SHOOTING 6-7 Mixing Characters to MONITOR OUT

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. Note: When a subject illuminated by a halogen lamp with a color temperature of 3,200K is shot while the color temperature conversion filter setting is set to 5,600K + ND, a proper white balance adjustment and (FAW) Full Time Auto White balance may not be accomplishable. In this case, change the color temperature conversion filter setting to 3,200K and then carry out the white balance adjustment and (FAW) again.

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

FULL-TIME AUTO WHITE BALANCE (FAW)
The FAW function adjusts the white balance value
automatically 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 item "FAW" on the

OPERATION MENU.

This item allows allocation of the FAW function to one of the WHT.BAL switch positions, A, B or PRESET.

☞ See "OPERATION SCREEN" on page 79.

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.

•ERROR: LOW LIGHT (Insufficient illumination)

Displayed when the illumination is dim. Increase the illumination 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.

CAUTION:

•The FAW (Full-time Auto White balance) function cannot provide 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-time Auto White balance) is inferior to that of the manual white balance.

•When the power is turned on with the FAW mode selected, it takes about 10 seconds for the FAW adjustment to be completed. Do not shoot within this interval.
