Editing Gradation Tables
When you open the Gradation Tool window, the default gradation table,
DefaultTable
, is selected in the Gradation Table list, and is displayed in the
graph. This table serves as a baseline and consists of a 45° gradation curve,
with Brightness and Contrast set to
0
, and Contrast Center set to
50
. All of
the color separations are selected.
Gradation tables that you create also appear in the
Gradation Table
list.
When you select a gradation table, the predefined settings are immediately
applied to the processed job that you are working with.
The separations buttons enable you to select one, all, or any combination
of separations to edit for a specific gradation table. Selecting a specific
separation enables you to change the color balance for a specific tonal
range.
