6.3.14 The Healing Brush 
The
Healing Brush is similar to the Copy Brush. You have to mark the
source area by holding Alt first, too. But while the copy brush is copying the
source pixels unmodified to the destination, the healing brush is transferring
only the changes in color and brightness und adjusts the source pixels to the
destination. Because of this the healing brush is perfectly suited to remove
unwanted parts of an image.
When working with the healing brush you should keep a few points in
mind:
- PhotoLine automatically expands the copy area by a smooth edge.
Therefore, it is usually better to use a "hard" brush.
- Because of this automatic smooth edge, your painting should exactly
cover the area, that you want to correct.
- The width of the smooth edge depends on the size of the brush. A small
brush creates a narrow smooth edge.
- As the Healing Brush adjusts the brightness and the color automatically,
you rarely have to reset the source point. If you want to - for example -
remove pimples or moles from a face, it is usually sufficient to set the
source point once and use it many times.
- It is often better to make several small corrections than a larger one.
- The Healing Brush can work with multiple layers. If you create a new
empty layer with transparency above the one you want to correct, you
can paint all corrections directly into this new layer. The original image
will not be modified.
