To see the effects of the curves on color balance:
1 Open the CC Basics UI.
2 Under Balance, adjust the Hue and Gain to set the color balance for each
of the Shadow, Midtone, and Highlight ranges.
3 Go back to the Ranges controls and set the curves.
4 Go back to the CC Basics controls. Without changing the color balance
setup, note that the resulting image is different from that in step 1.
The difference is the result of the changes that were made to the curves
of the shadows, midtones, and highlights.
Clamp Color Tool
The Clamp Color tool lets you clamp colors that are outside a given color
gamut. This is useful when you want to clamp an HDR image before using it
with certain esoteric blend modes in a composite or when you want to clamp
negative color components before using other color correction tools. Most of
the time, you will want to clamp colors against the conventional [0,1] range,
so this is the default behavior of the tool. This tool is an image modifier; it
can be masked and muted and can only affect the RGB channels.
The Clamp color tool has the following parameters:
To:Use:
Set the minimum color values in the image to be clamped.Min
Set maximum color values in the image to be clamped.Max
As an aid in visualizing which pixels are affected by its operation, this tool
has two secondary outputs: It generates a one-channel image (a mask) where
all out of range pixels are set to one and the rest are set to zero. It generates a
pseudo-color image (a map) where all pixels that are below the range are
