Using the Grade Panel
The Grade panel allows quick grading of all grade nodes within your project. This panel will list any grade node, whether it was created automatically or manually. You can access this panel in the Comp workspace by default, or by selecting Grade in the Choose panel... dropdown when creating or editing a panel.
Clicking on a grade node in this list will give color wheels for each of Lift, Gamma and Gain. There are also sliders to change each color using RGB, HSV or TMI color models.
Copy and paste values from each color wheel by right clicking on the parameter name (i.e. on the names Lift, Gamma or Gain).
To have more than one Grade panel open at once, press Ctrl+Left Click on the nodes in the left-hand menu for multi-selection. You will then be able to access each node on one panel.
