Adjusting the white balance
To reproduce white accurately, adjust the
proportion of the primary colors RGB. When the
white balance is wrong, not only the reproduction
of white is bad, but also the color tone of the whole
screen becomes bad.
When shooting in manual mode, if light conditions
change, always adjust the white balance.
The adjusted value for white balance can be saved
on the <A> and <B> positions of the <WHITE BAL>
switch.
Also, you can use the preset values already in the
memory. Use the memory according to shooting
conditions.
