6. SETTING AND ADJUSTMENTS BEFORE SHOOTING 6-5 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. 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, 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. WHITE BALANCE ADJUSTMENT 2. FILTER knob 1. IRIS mode switch Two kinds of white balance adjustment results can be stored in memories AUTO1 and AUTO2. Ⅲ Adjustment procedure 1.

Place a white object near the centre of the screen under the same lighting conditions as the target subject and zoom in to fill the screen with white. 5. Tilt the AUTO WHT./ACCU FOCUS switch upward (to AUTO WHITE) once and release it. "AUTO WHITE A, B OPERATION" is displayed in the viewfinder while the auto white balance adjustment circuit operates. When the white balance has been adjusted correctly, 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. • 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) Excessive illumination FULL-TIME AUTO WHITE BALANCE (TFhAe WFA)W 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. Ⅲ 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 73. 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. 45
