To adjust the shadows and highlights to improve contrast:
1 Click Basics to display the Basics menu.
2 Enable Plot and then Ctrl-drag the cursor over the portion of the result clip containing black or white.
In the Basics menu, a red plot line is displayed in the 2D luma histogram indicating the luma value of
the sampled blacks. In the vectorscope, you can view the saturation and hue.
3 Use the 2D luma histogram and 2D vectorscope to determine which controls you need to use (such as
the Black field, and Shadows and Midtones trackballs).
4 While viewing the 2D luma histogram, adjust the black level to modify the luma value. The Plot sample
is updated as you drag the field.
5 While viewing the 2D vectorscope, drag the Midtones and Shadows (Highlights) trackballs towards
the colour you want to increase in the blacks or whites. The Plot sample is updated as you drag the
trackball.
TIP To achieve true black or white, drag the Midtones and Shadows trackball to move the plot sample to
the centre of the 2D vectorscope.
6 Continue modifying the shadows until you are satisfied with the result.
TIP View the sample in the 3D vectorscope to make more refined modifications.
Increasing Saturation
When an image is desaturated, the colours can appear washed out. To improve contrast, you can increase
the colour saturation globally, saturate specific hues, or do both. Increasing saturation levels increases the
colour intensity and causes minor changes to the hue. The luma content is virtually unaffected when you
modify saturation.
To increase saturation globally:
1 Click Basics to display the Basics menu.
2 Drag right in the Saturation field while monitoring the 2D or 3D vectorscope and the image.
The selected colour range (or entire image) moves towards the perimeter of the 2D luma histogram.
There is also an increase in colour saturation in the image.
