To Adjust the White Balance

You will need a white balance card that you can zoom in on to take up at least 1/5 of the screen width and hight. The card should be placed in the same lighting conditions as the scene you want to shoot, without any high luminosity sources (such as a spotlight) in the scene.

The White Balance (WB) adjusts the colors in the image to compensate for various light sources that can tint the image. White will appear as white, without other color tints, when the image is properly white balanced.

Tip: You should adjust the white balance whenever there has been a change in lighting conditions.
  1. Ensure that the filtering is set for the current lighting conditions.
  2. Press MENU and select COLOR > WHITE GAIN > W. BAL MODE and select MEMORY.
  3. Zoom the camera in on the white balance card and adjust the iris control as required.
  4. Press MENU to close the menu system and hold the L button for 2 seconds.

    The camera will adjust the white balance automatically over several seconds. When the adjustment is complete the display will show the results of the white balance adjustment. Refer to Table 1 for a list of messages.

  5. Take any corrective action and repeat the procedure if required.
