Applying Softness Using a Uniform Gradient
 
 
 

Use the Softness fields to apply a constant range of softness to the edge of the mask. The Alpha and Offset fields define the fade-out of the softness gradient from the edge of the mask.

Once gradient transparency and offset have been determined, the degree of smoothness can be set using the Inner Edge and Outer Edge fields. You can then use the Distance field to determine the area where Inner Edge and Outer Edge settings have an effect.

To apply uniform softness:

  1. Access the Garbage Mask menu.
  2. Select a mask in the image window.
  3. If necessary, toggle the Edge Softness box to Softness.

  4. Set the border of the softness gradient using the Offset field. The gradient will be affected by how far the softness border is offset from the edge of the mask.
  5. Set the transparency of the gradient using the Alpha field.
  6. Use the Inner Edge field to smoothen the softness gradient towards the inside.
  7. Use the Outer Edge field to smoothen the softness gradient towards the outside. Adjusting this value is especially noticeable if you are smoothening a transition from a black inside edge to a white outside edge.
  8. Use the Distance field to modify the area of which the Inner and Outer Edge adjustments have an effect.
