You
            can set the inversion threshold of an image to create solarizing
            effects.
         
         To solarize an image:
         
         
            - From the Tools tab, drag the Solarize
               tool from the Color Correction folder to the dependency graph in
               the Schematic view. 
               The Solarize tool UI
                  appears with the Threshold set to zero and the image inverted (by
                  default).
                
- Adjust the Threshold to change the amount
               of solarization.
