The Histogram Scan Node is very similar in behavior to a Mari Contrast Node but lets you work with values

you are familiar with from Allegorithmic's Substance Designer.

• Position

Defines the Midpoint on the histogram from which to contrast from

• Contrast

Defines the Bracket around the 'Position' for Black & White Point

• Invert Position

Inverts the Position Value. So for example a Position of 0.9 becomes a position of 0.1

• Clamp

With Clamp turned on no values above 1 and below 0 will be output as a result of the Node.
