paper or cloth and press .
zIf you are viewing it with the LCD monitor, ensure that
the center frame is completely filled with the white
image. If you are using the optical viewfinder, ensure
that the entire field is filled. However, the center frame
will not appear when the zoom factor is 5.0x or higher
or when is displayed.
zYou are recommended to set the shooting mode to
and the exposure compensation setting to [±0] before
setting a custom white balance. The correct white
balance may not be obtained when the exposure
setting is incorrect (image appears completely black or
white).
zShoot with the same settings as when reading the
white balance data. If the settings differ, the optimal
white balance may not be set. In particular, the
following should not be changed.
- ISO Speed
- Flash: Setting the flash to on or off is recommended.
If the flash fires when reading the white balance data
with the flash set to (Auto) or (Auto with
red-eye reduction), make sure that you also use the
flash when you shoot.
zSince the white balance data cannot be read in Stitch
Assist mode, preset the white balance in another
shooting mode beforehand.
