Linear Mode: Selecting Levels of the Image			Linear Mode: Modifying Gain
Chapter 13, Primary Colour Grading

You can lift colour values in a selected range or in the entire image, and then offset ranges of colour. Changes in lift mostly affect black level. Although lift affects the entire image or image level, visually, it mostly affects the shadows.

Note: When you use a slider or colour balance wheel to colour grade a shot, the colour range is limited by the control (the edge of the colour wheel, for example). Use the Autodesk control surface or the Tangent CP100 control surface to reach the full spectrum of colour.

1. Indicate whether this is the initial or final primary grade:

   • To work on the initial primary colour grade, click Input.

   • To make final adjustments to the primary colour grade, click Output.

2. Select the image level you want to modify.

   

3. Modify the black levels:

   • To increase the black level, drag the Lift slider up.

   • To decrease the black level, drag the Lift slider down.

   

4. To offset the colours while maintaining the overall luminance, enable Lift and then drag the Lift Balance wheel towards a colour.

   

   The selected colour is lifted while other colours in the image are offset to compensate for the change in luminance.
