Fine-Tuning White Balance
At settings other than PRE (preset), white balance
can be “fine tuned” to compensate for variations
in the color of the light source or to introduce a
deliberate “warm” or “cold” cast into an image.
Higher settings can be used to lend images a blu-
ish tinge or to compensate for light sources with
a yellow or red cast, while lowering white balance can make photographs
appear slightly more yellow or red or compensate for light sources with a blue
cast. Adjustments can be made in the range +3 to –3 in increments of one.
In Auto mode, each increment is equivalent to about 10 mired. At other
settings, white balance is adjusted as shown below:

* The camera color temperature setting may differ from the value for color temperature
measured with a photo color meter.
† The size of the increments for Fluorescent reflects the wide variations in color tem-
perature among the many different types of fluorescent light source, ranging from
low-temperature stadium lighting to high-temperature mercury-vapor lamps.
