Using AIC Tools 4-11

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.
