To calibrate the camera, press the function button and turn the con-
trol dial until the custom white-balance icon and "SET" appear on
the data panel and red on the monitors. While holding the function
button (1), use the up/down keys of the controller (2) to select one
of the three memory registers. Select a white object and fill the
image area with it; the object does not need to be in focus. Press
the shutter-release button to calibrate the camera.
If an error occurs during calibration, an error message will appear
on the monitors. Press the controller to cancel the message; the
custom white balance icon will turn yellow to indicate the error.
Recalibrate using a suitable reference target and the shutter-
release button. This sequence can be repeated as many times as
necessary.
The setting will remain in the selected register until it is replaced with another calibration. If the cus-
tom white-balance setting needs to be used again, while pressing the function button, turn the control
dial until the custom white-balance icon is displayed without the "SET" on the data panel and white
on the monitors. While holding the function button (1), use the up/down keys of the controller (2) to
select one of the three memory registers.
The built-in flash can be used with the custom setting. However, since the flash is daylight balanced,
it will give an unusual color cast to an image if the camera is calibrated to any other light source.
Shooting tips
When making the calibration, the color of the object used is critical. The object should be white.
A colored object will cause the calibration to compensate for the object color rather than the
color temperature of the ambient light. A blank piece of white paper is an ideal surface and can
easily be carried in a camera bag.
A calibration error may occur under extremely bright light sources, especially with high-power
flash units. Use a gray card as the calibration target to reduce the intensity of the illumination.
The aperture can also be stopped down in the manual exposure mode to control the light.
