Performing Hue Shifts
You can use the Hue field in the Basics menu to perform hue shifts on the entire image or a range in the
image defined by a selective's matte. Perform hue shifts when you want to change the colour of an object
or create other artistic effects. Hue shifts do not affect the luma.
You can also perform hue shifts when you want to suppress colour spill. See
Removing Colour Spill (page
835).
To perform a hue shift:
1 If necessary, create a matte for the range of colour you want to change. See
Selecting Colour Ranges
for Colour Correction
(page 815).
2 Click Basics to display the Basics menu.
If you are using a selective, the Selective View box should display Result when you display the Basics
menu.
3 Sample the image to see the hue shift in the 2D luma vectorscope. Enable Plot and then sample the
colour range in the image you want to hue shift.
A red line also appears in the 2D luma histogram and the sample is outlined in the 2D or 3D vectorscope.
4 Drag the Hue field while monitoring the 2D or 3D vectorscope and the image.
The selected colour content (or entire image) shifts through the colour range.
5 If necessary, you can change the saturation of the hue by dragging the Saturation field—drag right to
increase saturation or left to decrease it.
The selected colour range moves towards the perimeter or centre of the 2D luma histogram.
Creating Colour Casts
You can use the Midtones trackball to create a colour cast that affects the chroma in the entire image without
affecting the luma. Create a colour cast when you want to emphasize a colour range to create an artistic
effect or when you want to refine an existing cast. For example, create or refine a bluish cast to convey a
cooler atmosphere.
NOTE Before you create a colour cast, you should correct colour imbalances in the image or clip. See Correcting
Colour Imbalances
(page 821).
