Contrast

Increases or decreases contrast of values using a linear slope multiplier.

Parameter Types

Parameter descriptions

In

The input value to modify.

Amount

The linear slope multiplier that increases or decreases the contrast. A value between 0.0 and 1.0 decreases the contrast of the In parameter, while a value greater than 1.0 increases it.

Pivot

The center value of the contrast adjustment. As contrast increases, values of the In parameter get further away from this value. As contrast decreases, values of the In parameter get closer to this value.

Discussion

Below is an example of a node graph that uses the Contrast node to make a black and white arrow texture more gray and closer in color.

Below, the resulting texture applies to a cube:

In the image above, the value of Pivot is 0.2, which represents a dark gray. Because the value of Amount is also 0.2, the contrast of the input decreases while the color value of the texture moves closer to the Pivot input. As a result, the output texture of the node becomes a gray version of the original black and white arrow texture.
