Improving Contrast Using Gamma
 
                
               
             
             
            
            Increasing Saturation
          
       
       
       
       
      When an
         image is desaturated, the colours can appear washed out. To improve
         contrast, you can increase the colour saturation globally, saturate
         specific hues, or do both. Increasing saturation levels increases
         the colour intensity and causes minor changes to the hue. The luma
         content is virtually unaffected when you modify saturation.
      
      To
         increase saturation globally:
      
      
         - Click
            Basics to display the Basics menu.
         
- Drag
            right in the Saturation field while monitoring the 2D or 3D vectorscope
            and the image.
            The selected colour range (or entire image)
               moves towards the perimeter of the 2D luma histogram. There is also
               an increase in colour saturation in the image.
             
To
         saturate specific hues of an image:
      
      
         - Click
            Basics to display the Basics menu.
         
- Select
            Saturate from the Trackball option box.
         
- Drag
            the Saturate trackball towards the colour you want to saturate while
            monitoring the 2D vectorscope. Drag until the colour is closer to
            the edge of the 2D vectorscope. For example, to saturate reds, move
            the trackball towards red.
            NoteTo make the trackballs respond to changes
                  in pressure, use the Pointer preferences in the Preferences menu.
                  See  Pointer Preferences.
                
 
- Release
            the trackball.
         
- To
            further increase the saturation of the same colour, use the trackball
            to move the colour closer to the edge of the 2D vectorscope.
