NOTE You can animate the curve using the Shape channel under Midtone in the Channel Editor. Click Animation
to view the Channel Editor.
Highlights trackball Modifies the chroma in the high luminance area without affecting the luma.
To remove unwanted colour using the Shadows, Midtones, and Highlights trackballs:
1 Click Basics to display the Basics menu.
2 Enable Plot and then sample the image's highlights.
The sample (outlined in red) appears in the 2D or 3D vectorscope.
TIP You can determine the colour of a sample by dragging right in the Saturation field to temporarily increase
the saturation while monitoring the sample in the 2D vectorscope. When you release the mouse, the level
that appears in the field resets to its default reference value. Once you determine the cast of the colour, click
Undo to reset the saturation level and then resample the image.
3 If necessary, double-click the 3D vectorscope to display the 2D vectorscope.
4 While viewing the 2D vectorscope, drag the Highlights trackball to move the sample towards the centre
of the 2D vectorscope.
The chroma in the high luminance area of the clip is modified without affecting the luma.
5 Drag the Midtones trackball to make minor adjustments to the chroma content.
TIP Drag the left midtones triangle to decrease the range affected by the Midtones trackball. Make sure the
range includes the sampled colour.
The RGB curves in the 2D luma histogram reflect the changes you make. More of the unwanted colour
is removed from the image (while still preserving luma) without affecting the black and white points.
TIP To achieve true white, drag the Highlights and Midtones trackball to move the plot sample to the centre
of the 2D vectorscope.
6 Continue modifying the highlights and midtones until you are satisfied with the result.
7 Enable Plot and then sample the image's shadows.
8 Repeat steps 2 to 6 using the Shadows and Midtones trackballs to remove unwanted colour from the
shadows (and midtones) in the image.
