Set Range (Non Uniform)


  • Where to find it:


    • Add Adjustment Layer / Extension Pack / Color Correction / 


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




The setRange (Non-Uniform) Adjustment is a value remapping tool similar to the standard setRange Node

Other than the normal setRange node, the non-uniform variant allows you to remap a linear value progression

to a non-linear value one.



Node Overview




Node Properties


MAIN TAB

Main


  • OldMin

The value that is defined as Minimum Value on the Input Color. For example on a gradient black to white, when increasing the OldMin

any incoming Value below OldMin will become black.


  • OldPivot

The value that is defined as (arbitrary) mid-point of the value range between min and max. 


  • OldMax

The value that is defined as Maximum Value on the Input Color. For example on a gradient black to white, when decreasing OldMax

any incoming Value above OldMax will become white.


  • NewMin

The value that is defined as Minimum Value on the resulting Output. For example on a gradient black to white, when increasing NewMin

the previously black areas will be the value set in NewMin.


  • NewPivot

The value that is defined as the new (arbitrary) mid-point of the value range between min and max. 


  • NewMax

The value that is defined as Maximum Value on the resulting Output. For example on a gradient black to white, when decreasing NewMax

the previously white areas will be the value set in NewMax.


Extra Attributes


  • MultiplyScale

MultiplyScale multiplies against the sliders of OldMin,OldMax,NewMin & NewMax.

By setting values over 1.0 you can create or adjust floating point output (16bit,32bit channels).


  • Clamp Intermediary

When ticked on the the result of the OldMin and OldMax will be clamped first before getting passed

to the NewMin and NewMax settings.

This will more reliably keep values exactly within the range of NewMin and NewMax for example

when the OldMax was lowered below 1.0 etc.


  • Clamp Output

When ticked on the Output of the Node will always be clamped to 0 - 1 regardless if the NewMin is lower than 0,

or the NewMax is higher than 1.

If you are using 16bit float or 32bit values you should untick the OutputClamp



CHANNELS TAB

Channels


  • R / G /B / Alpha

Determines which channels are affected by the remapping operation. Default is RGB with Alpha being unaffected.
