Use the White & Black Points tool to
set the shadow and highlight points of
an image, as well as to neutralize the
color cast in shadow/highlight regions.
In the example below, the original has a
slight color cast in the shadow and
highlight portions of the image. With
the use of the auto neutralizing and
auto adjustment features, the color cast
is removed, and the shadows and
highlights are remapped accordingly.
The shadow point is defined as the lightness value “L” in an image that is output as
black (mapped to the Minimum Output Level), while the highlight point is defined as
the lightness value “L” that is output as white (mapped to the Maximum Output Level).
The default values of the Minimum Output Level and Maximum Output Level are
L=5.0 and L=95.0, respectively.
