Appendix A, The Autodesk Control Surface

When the Curves menus is enabled, you can use the Function panel to:

• Modify Hue and RGB curves either after the initial primary colour grade, or after the addition of any Lustre Sparks® effects.

• Adjust the Hue, Lightness, Saturation, and Luminance curves separately.

• Modify the entire curve uniformly or modify individual vertices for RGBCMY channels (red, green, blue, cyan, magenta, and yellow).

1. Press Curves on the Navigation panel.

   The In Primary, Out Primary, Hue, and RGB options are activated.

   

2. Do one of the following:

   • Press the F1 option button to indicate that you are working on the initial primary grade.

   • Press the F2 option button to indicate that you are working on final curve modifications.

3. Do one of the following:

   • Press the F3 option button to work on Hue curves.

   • Press the F4 option button to work on RGB curves.

4. On the Function panel, use the following controls.
