Color Curve Graph

The graph below the color channels list represents the color correction curve. Input
values are represented along the x‐axis and shown numerically in the In(put) edit
box. The adjusted output values are represented along the y‐axis and the adjusted
output values are shown numerically in the Out(put) edit box.
If the Color profile option is set to Standard Mode, this curve changes dynamically
as you adjust the Contrast, Brightness, or Gamma values using the sliders.
If the Color profile option is set to Advanced Mode, you cannot use the Contrast,
Brightness, or Gamma sliders but you can modify this curve in real‐time by using any
one of these methods:
• Click the curve to create a control point on it. Repeat the step to create additional
points, as needed.
• Click the curve and drag the mouse to modify the curve, which also dynamically
modifies the values in the Input and Output edit boxes.
• Enter a value that is less than or equal to 1 in the Input and/or Output edit boxes.
• Select one or more control points and then press the arrow keys on your keyboard
to adjust the curve and numeric values in the Input/Output edit boxes.
• To insert several control points, click the curve to select a point and then press Ins
(Ins key on your keyboard) one or more times, depending on the number of points
you want to add, which is limited by any other points that may already exist on
the curve.
• To remove a control point, select the point and drag it out of bounds or select the
point and press Del.
• To select multiple control points, you can either press down the Ctrl key and select
the points you want with your mouse, or left click and drag the mouse around the
items to create a box that selects the items.
If you have loaded an ICC profile, the color correction curves loaded from the ICC
profile are displayed in the graph. Use a professional publishing application to
perform color matching based on information in the ICC profile.
