setting.
X The Custom WB data will be
registered to the camera.
To use the Custom white balance,
see “Selecting and Shooting with the

(p.183).
If the exposure obtained in step 4 differs greatly from the standard
exposure, a correct white balance may not be obtained.
Custom WB data can also be registered as follows:
1. Press the <
B > button and turn the < 5 > dial to select < O >
(p.177).
2. Then turn the < 6 > dial to select the number under which the
Custom WB is to be registered.
3. Press the < J > button.
9 The number selected in step 2 will blink on the top LCD panel.
4. Follow step 4 above to photograph a solid-white object.
9 The Custom WB data will be registered under the selected
number.
If [ Correct WB may not be obtained with the selected image ] is
displayed in step 4, go back to step 1 and shoot again.
The image captured in step 4 will not be recorded to the card.
Instead of a white object, shooting a gray chart or 18% gray reflector
(commercially-available) can produce a more accurate white balance.
