White balance and black balance Adjusting the black balance There is normally no need to re-adjust the black balance. Adjustment is required only in the following cases. OWhen the camera recorder is to be used for the first time OWhen the camera recorder is to be used after it has not been used for an extended period OWhen the camera recorder is to be used in a situation where the ambient temperature will vary significantly OWhen the standard (OFF) shutter speed or slow shutter mode has been selected OWhen the progressive mode has been switched to the standard (60i) mode or vice versa The white balance is adjusted automatically by pressing the AWB button. If the button is then held down, the black balance is adjusted. OWhen the AWB button is pressed, the white balance is adjusted first. Therefore, ensure that the conditions under which the white balance is adjusted are satisfied before pressing the button. OWhile recording is in progress, the black balance cannot be adjusted. ATW (Auto Tracking White) function The ATW function can be allocated to the WHITE BAL switch (A, B or PRST position) using the ATW item on the setting menu SW MODE screen. (See page 43) Similarly, the ATW function can be allocated to the AUTO button using the ATW item on the setting menu AUTO SW screen. (See page 44) When material is shot using the ATW function, it is recorded while the white balance is being continually adjusted automatically. OThe ATW function automatically identifies the shooting environment and adjusts the white balance optimally. In some environments, a slight adjustment error may arise. If an extremely accurate white balance adjustment is required, adjust the white balance by following the instructions on the previous page.
