Taking Photographs—White Balance
White Balance
Keeping Colors True
The color of 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 in for -
ma tion from the 1,005-pixel RGB sensor, LBCAST image sensor, and ambient
light sensor 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. The following options are available:
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. In auto and preset modes, the
cam era uses “through-the-lens” (TTL) white balance measurement to ensure
that white bal ance is set correctly even when the camera and sub ject are
under different lighting.
