Chapter 23 Color Correction 645
Parameters
This node displays the following control in the Parameters tab:
value
A slider that defines the saturation multiplier.
Solarize
The Solarize node is a partial inverse that reverses the high or low end, depending on
the value of the hi/lo flag. With values above (“hi,” or 1) or below (“lo,” or 0 ), the
thresholds are reversed. The resulting images are similar to a photographic effect
popular in the 1960s, where the print is exposed to light during development and
results in an image with blended positive and negative value ranges. It gives a metallic
effect to color images.
Parameters
This node displays the following controls in the Parameters tab:
value
The point at which the image is inverted.
thresholdType
Determines whether numbers must be higher or lower than the Value parameter to be
affected by the Solarize operation.
• 0 means “lo,” or below the threshold value that the color is inverted.
• 1 means “hi,” or above the threshold.
Threshold
The Threshold node cuts channels off at a certain value, and turns everything below
that cut-off value to 0. Each channel can have its own separate cut value. By using the
crush parameter, you can boost everything above the value 1.
