You can use the Autodesk control surface to perform input and output grading in Logarithmic or Linear mode.

As with other menus, you select the Grade menu from the Navigation panel. This activates colour grading functionality on the Function panel. The Colour Grading panel is enabled regardless of which menu is active in the Function panel. The features available on these panels depend on whether you are in Logarithmic or Linear mode. You specify the colour architecture in the Setup Grade menu in the user interface.
