How to use the automatic tracking white (ATW) balance mode

The automatic tracking white balance mode is established when the white balance selector switch (AUTO W/B BAL) is set to the ATW position. However, since the ambient light conditions may make the auto tracking white balance operation unstable, learn how to use the MEMO, PRESET and ATW modes to best suit the prevailing conditions.

Examples

OWhen shooting a subject illuminated by a spotlight, proceed in the

PRESET (INDOOR mode).

OIf you know ahead of time that you will be shooting a subject outdoors, store the white balance setting in the MEMO position.

OShooting a subject illuminated by a mixture of light from fluorescent lighting and incandescent bulbs or by a mixture of outdoor light and fluorescent lighting because the subject is by a window presents difficulties for automatic tracking. Under conditions such as these, adjust the white balance manually.

Use the ATW balance mode only in an emergency when you do not have the time to adjust the white balance manually.

The white balance adjustment is completed is about 10 seconds.

OUpon completion of the adjustment, the color temperature display appears in the viewfinder.

Now check that the color temperature imaged and the color temperature displayed in the viewfinder match. If they do not tally, it is recommended that the white balance be adjusted again.

OIf it was not possible to adjust the white balance, the WHITE BAL ERROR TRY AGAIN message appears in the viewfinder. In a case like this, check that the lens cable is connected properly and that the subject brightness is suitable, and then adjust the white balance again.

 

When the white balance should be re-adjusted:

 

Be absolutely sure to re-adjust the white balance when there has been a

 

change in the light conditions or when the gain setting has been changed.

Notes:

 

$ Since hunting may occur when a zoom lens with an automatic iris

 

mechanism is used, adjust the iris gain knob provided on the lens.

 

For further details, refer to the operating instructions

 

accompanying the lens.

 

$ The white balance cannot be adjusted if the white balance selector

 

switch is set to the ATW or PRST position.

 

$ Do not allow a subject lighter than the white object shot in step 3

 

above onto the screen since the white balance is adjusted with the

 

lightest part of the subject on the screen taken to be white.

 

Failure to heed this caution may cause malfunctioning.

 

$ Do not increase the gain to an unnecessarily high value and then

 

proceed with the automatic white balance (AWB) operation.

 

Failure to heed this caution will cause the iris to be nearly stopped

 

down when AWB is performed so operation will become unstable.

Remarks: $ In order to ensure that a high picture quality is maintained, it is recommended that AWB be performed immediately before shooting scenes of great importance or value.

$ When the white balance is adjusted, the black balance is also adjusted automatically inside the unit. Consequently, when the AUTO W/B BAL switch has been operated, the iris will close before opening again: this is normal and not indicative of any malfunctioning.
