Shooting Black balance adjustments In order to reproduce the black accurately, adjust the zero level of all three RGB primary colors. If the black balance is not adjusted properly, not only will the black be reproduced poorly but the color tones of the entire screen will also be downgraded. It is not normally necessary to adjust the black balance. Adjust it when: • You use the camera for the first time. • You use the camera after not using it for a long time. • The ambient temperature changes greatly. • You change the gain and shutter speed. • You switch to the CAM mode from the PB mode. • You change the SYSTEM FREQ. Auto Tracking White (ATW) Using the ATW function enables the recording environment to be automatically analyzed and an optimum white balance to be constantly maintained during recording. You can allocate the ATW feature to one of the positions on the WHITE BAL switch (A, B, or PRST). Allocate it by going to the setup menus, SW MODE screen, ATW. (Page 54 of Vol.2) White balance sensor White balance can be adjusted automatically by pressing the AWB button, while black balance can be adjusted by holding the button down. Set the conditions for white balance adjustment before proceeding. Message during adjustment ABB ACTIVE Message after adjustment ABB END • Black balance can be adjusted by holding the AWB button down even when the ATW function is in use. • You cannot adjust the black balance while you are shooting. • Black balance adjustment takes around 30 seconds when the shutter speed is 1/8 or less. • Depending on the environment, there may be some error in the adjustment. • Use the procedure described on the previous page whenever you need more precise white balance. • Do not block the white balance sensor when using the ATW feature. ATW will not work if you do. 43
