Setting the Softness Range

After you choose a colour model and set the average colour, adjust the softness range. The softness at the edges of the matte increases as you increase the softness range. To set the softness, you can use the colour picker, the numeric fields, or the Master Softness field.

To set the softness using the colour picker:

1. Zoom in to see the edges of the matte more clearly.
2. Click Softness in the selected colour model menu.

   The cursor changes to a colour picker.

3. Position the colour picker at the edge of the matte. To increase the softness, click and slowly drag the colour picker toward the centre of the matte. The values within the area you selected are used to adjust the maximum and minimum values for the softness range. The positions of the yellow lines change as you drag the cursor on the image.
