Color Saturation=2.0
Whitepoint Specifies the main color temperature of the light sources. This
is similar to white balance controls on digital cameras. For daylighting, a value
of 6500 is recommended, for incandescent lighting, a value of 3700 is
recommended.
For example, photographs taken indoors might be lit by incandescent lights,
which are relatively orange compared to daylight. Defining "white" as daylight
will give unacceptable results when attempting to color-correct a photograph
taken with incandescent lighting.
Vignetting Reduces the image brightness in the image periphery compared
to the image center, resulting in a circular fully exposed area in the center,
with darker edges.
