Taking Photographs—White Balance
White Balance
Keeping Colors True
The color of the light refl ected from an object varies with the color of the light
source. The human brain is able to adapt to changes in the color of the light
source, with the result that white objects appear white whether seen in the
shade, direct sunlight, or under incandescent lighting. Unlike the fi lm used in
fi lm cameras, dig i tal cam er as can mimic this adjustment by processing images
according to the color of the light source. This is known as “white balance.”
For natural coloration, choose a white bal ance set ting that match es the light
source before shooting. When the mode dial is set to
P , S , A , or M , white
balance can be selected from the following options:
* Fine-tuning set to 0.
Auto white balance is recommended with most light sources. If the desired
results can not be achieved with auto white balance, choose an option from
the list above or use preset white balance.
