You can match and colour correct the colours of the front clip using the back clip as a reference. To perform a match operation, sample colours from the front and back clip and then use the Match button in the Curves menu.

To match colours between two clips:

1. Load a front and back clip from the EditDesk.
2. Use the split bar to view the front and back clips in the image window. See Displaying the Reference Area.
3. Click the Curves tab to display the Curves menu.
4. Click the Front colour patch.

   
   

   The colour picker appears.

5. Using the colour picker, select a colour in the front clip to be corrected.

   The colour is added to the Front and Result colour patches.

6. Click the Back colour patch.

   
   

   The colour picker appears.

7. Using the colour picker, select a colour in the back clip to use as a reference colour.
8. Click Match.

   
   

   The reference colour is applied to the result clip. The reference colour is also added to the Result colour patch and points are added to the colour curves.

   When you use Match, a number is displayed in the numerical field beside the Rematch button. The first match you perform is indicated by a 1 in the field, the second by a 2, and so on. To revert to a previous match, click the numerical field and type the number of the match you want to recall. The colour patches and colour curves reset to the values stored in the specified match.

   To reset the red, green, blue, or luminance curve, select a curve and click Reset in the Curve menu. The Curves menu also has its own Undo button that is separate from the overall Colour Corrector Undo.
