Contrast Node
Access: Nodes > Filter > Contrast
The Contrast node is a filter node that adjusts the input data by linearly adjusting the difference in luminosity between the light and dark areas of a source texture.

Contrast Node Inputs
Input - Any nodes containing textures or paint that need to be altered can be connected to the Contrast node, for example, Tiled and Paint nodes.

Contrast: Node Graph Workflow Example
Example - Achieving Contrast Operation
In the example below, let’s use a Contrast node to emphasize the dark brown pigments of the model.
| 1. | Add a Paint node. | 
                                                        
                                                    
Adding a Paint node.
This is the original texture.
The model has some dark brown pigments on his face.
| 2. | Create a Contrast node.  Connect the Paint node to the input of the Contrast node.  | 
                                                        
                                                        
                                                    
Adding a Contrast node to the Paint node output.
| 3. | Open the node Properties of the Contrast node and set the Contrast parameter of the Contrast node to 1.200. | 
Notice how the dark brown pigments now look darker.
Contrast node’s Contrast set to 1.200. 
                                                        
The dark brown pigments now look darker.
