Custom-white-balance function allows the camera to be calibrated to a specific lighting condition.
Three setting can be stored in the camera and used repeatedly. Custom white balance is especially
useful with mixed-lighting conditions or when critical control over color is needed.
Custom White-Balance Calibration
Select a white object and fill the center of the live image with
it; the object does not need to be in focus. Press and hold the
custom white-balance button to calibrate the camera; the
measuring area is briefly displayed before the shutter releas-
es.
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 sur-
face and can easily be carried in a camera bag.
Shooting tips
If an error occurs during calibration, a message will appear on the monitors. Press the controller to
cancel the message and press the menu button to cancel the register-selection screen; the custom
white-balance indicator will be yellow to indicate the error. Recalibrate using a suitable reference
target. A calibration error may occur under extremely bright light sources, especially with flash units.
Use a gray card as the calibration target to reduce the intensity of the illumination.
On the register-selection screen use the control dials or
left/right keys of the controller (1) to select the custom white-
balance register in which to store the setting; any previous
setting is replaced. Press the central button of the controller
(2) to complete the operation. The menu button cancels the
operation without saving the setting.
