6.3.17 The Red Eye Brush 
Red
eyes are a common problem in photography. The Red Eye brush can be
used to remove them. First you select the area that should be corrected.
After releasing the mouse button, the correction will take place. In the Tool
Settings Intensity allows to enlarge or shrink the area a bit. Brightness can
be used to make the result darker or brighter.
When working with the Red Eye brush you should keep a few points in
mind:
- PhotoLine automatically expands the correction 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.
- Intensity and Brightness can be used to optimize the result until you
execute another function or switch the active layer.
- The Red Eye 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.
