Modify color saturation and value in an image
 
 
 

This tool allows you to adjust the tonal range of an image by providing sliders for saturation and value. It also lets you compare the original image with a preview image showing the modifications as you change the slider values.

Example Workflow

  1. Import the image (File > Import > Canvas Image ) or pick the layer to be adjusted in the Canvas Layer Editor.
  2. Choose Paint Edit > Color Correction > Saturation & Value . The active layer is loaded into the Saturation and Value window.

    Decide what tonal value to change. In this example, we’ll increase the saturation of all the colors in the image to make the sketch more dramatic, and then decrease the saturation for only the midtones.

  3. Make sure the Adjustment Type is set to All Color Tones.
  4. Increase the saturation for all color tones by increasing the Saturation Factor until the bottom image looks correct.

  5. Press the Accept button.

    The changes are applied to the layer and the Saturation and Value window closes.

  6. Choose Paint Edit > Color Correction > Saturation & Value again to reopen the window.
  7. Zoom in and pan into the area of the image that has midtone colors (using the buttons at the top of the Saturation and Value window).

  8. Decrease the saturation for only the midtone colors by changing the Adjustment Type to Only Midtones, and decreasing the Saturation Factor until the bottom image looks correct. (You may also lighten the midtones by decreasing the Value Factor.)

  9. Zoom back out to see the overall effect of the change in the bottom image.

  10. Press the Accept button at the bottom of the Saturation and Value window.

    The changes are applied to the layer and the Saturation and Value window closes.
