Light has color to it, from the warm glow of a sunset to the cool bluish hue right
before the sun rises in the east. Our eyes and brains automatically adjust to this, so
we sometimes don’t pick up on the nuances of color when it happens. This is why,
when you walk from outside on a bright sunny day into a fluorescent-lit office, the
color remains amazingly consistent, even though the light sources are different.
The camera’s Auto White Balance (AWB) feature attempts to correct for such variation
in lighting, but as with any automatic feature, it’s not infallible. Although AWB can
provide acceptable results, I find that I achieve more accurate and consistent results by
setting the white balance to a preset or by creating a custom white balance.
When saving images as JPEGs, getting the white balance right is very important,
because it’s difficult to correct color after the fact. Raw files provide greater flexibility
because you can correct white balance easily in your photo-editing application
without compromising image quality. However, it’s always faster and simpler to get
the white balance correct at the moment of capture.
