Matching Specific Colours
 
 
 

You can match plot samples to reference samples using the trackballs and by aligning the colours in the vectorscope. For example, you may want to match a red in one image to a different shade of red in another clip. For information on using Plot and Ref controls, see Sampling Clips in the Image Window.

To match specific colours:

  1. Select Result from the View box.

    The result clip is displayed in the image window.

  2. If necessary, position the split bar so that both a reference clip and the result clip appear.
  3. Enable Plot and then sample a colour in the clip you want to modify (the result clip).

    A red plot line is displayed in the 2D luma histogram indicating the luma value of the sample. In the 2D vectorscope, you can view the saturation and hue of the sample (outlined in red). In the 3D vectorscope, you can view the sample in terms of HLS.

  4. Enable Ref and then sample the colour in the reference image you want to match.

    A yellow reference line is displayed in the 2D luma histogram indicating the luma value of the sample. In the 2D vectorscope, you can view the saturation and hue of the sample (outlined in yellow). In the 3D vectorscope, you can view the sample in terms of HLS.

  5. Use the 2D luma histogram in the Basics menu and 2D vectorscope in the image window to determine which controls you need to use.
    Drag: When:
    White or Black field You need to adjust the luma values in the highlights or shadows without modifying the chroma. Drag the field so that the plot line in the 2D luma histogram moves towards the reference line.
    Highlights, Midtones, or Shadows trackball You need to adjust the chroma values in the image without modifying the luma. Drag the trackball(s) so that the plot sample in the 2D vectorscope moves towards the reference sample.
  6. Use the necessary controls to modify the clip until the plotted sample is aligned with the reference colour in the 2D luma histogram and 2D vectorscope. If necessary, increase or decrease the saturation as well as shift the hue.
