As in Log mode, you can complete the task of balancing the shot's colours by modifying the contrast. With the Contrast slider, you can change the image's Linear luminance curve to a film-contrast-like S curve.

To modify image contrast:

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. Modify the image contrast:
   • To increase image contrast, drag the Contrast slider up.
   • To decrease image contrast, drag the Contrast slider down.
