Understanding how the color correction groups work together is important. Adjustments made in each group are applied cumulatively to the current segment and its related material. If you make an adjustment in one group and then go on to make another adjustment in a different group, the image will show the cumulative effect of both adjustments.
This behavior provides you with a great deal of flexibility. For example, if you are unhappy with some of your adjustments, you can disable the group that contains those adjustments or reset its controls to default settings without disrupting other adjustments.
For more information on enabling, disabling, and resetting the groups, see
Working with the Enable Buttons.
