Jitter Color


  • Where to find it:


    • Add Adjustment Layer / Extension Pack / Color Correction / 


    • NodeGraph / Right Mouse Click / Nodes / Filter / Extension Pack / Color Correction / 





The Jitter Color Node allows you to randomize Hue, Saturation and Value based on a supplied signal value

Please note that in order for the node to work, a jitter signal needs to be supplied via the Nodegraph Signal Port

Node Overview



Node Ports


  • Input

Supplies the Color or Texture that you want to jitter


  • Min / Max Saturation

A value for the minimum and maximum Saturation to jitter between. If these ports are mapped the corresponding

sliders in the node are no longer evaluated


  • Min / Max Hue

A value for the minimum and maximum Hue to jitter between. If these ports are mapped the corresponding

sliders in the node are no longer evaluated


  • Min / Max Gain

A value for the minimum and maximum Gain to jitter between. If these ports are mapped the corresponding

sliders in the node are no longer evaluated


  • Jitter Signal

This is the core value that needs to be supplied in order for the node to work correctly.

It can be for example a noise, material ID Map etc. that can be used as a blend value for

Min/Max Saturation, Hue and Gain


Please note, this Jitter Signal can be different for red, green and blue. The red channel is used as a signal

for Saturation Jitter, the green Channel for Hue Jitter and the Blue Channel for Gain Jittering.



Node Properties

MAIN TAB

Jitter Saturation


  • Min / Max Saturation Offset

The minimum and maximum Saturation to jitter between based on the supplied signal.

This is an offset value on the original Input,  meaning a Min/Max of 0 will give you the original Saturation


Jitter Hue


  • Min / Max Hue Offset

The minimum and maximum Hue Shift to jitter between based on the supplied signal.

This is an offset value on the original Input,  meaning a Min/Max of 0 will give you the original Hue


Jitter Gain


  • Min / Max Gain

The minimum and maximum Gain to jitter between based on the supplied signal.

The default (no change from Input) is 1.0


CellNoise


Cell Noise will run the Input Signal through a series of randomizations


  • Use CellNoise

When ticked the supplied signal will be run through a cell noise routine which will further randomize the values.

It works best when the input values aren't too noisy.


  • Saturation/Hue/Gain Seed

The Cell Noise Seed (random Value) for the Saturation, Hue and Gain


Clamping


  • Clamp Output

Will prevent the Output of the Jittering to go over values of 1
