Adjusting the White Balance Manually

You can adjust the white balance depending on the light source when
taking pictures. With the manual white balance, the camera can store
delicate shades that cannot be precisely adjusted with the white balance
preset values provided in the camera. This provides the optimum white
balance for your surroundings.
