258 Tutorial 9 Creating Clean Plates
5 If you paint too far to the left, and reveal the actors in frame 38, use the Eraser to tidy up.
Unfortunately, there is a small area where the actors overlap in the frames, and the
Reveal Brush cannot do the whole job. The Clone Brush can help you clean up that last
bit by copying some of the nearby color from the water.
To paint with the Clone brush:
1 Click the Clone Brush button.
2 Press the Shift key and drag to relocate the brush from the clone source.
You might need to paint a few strokes, adjusting the position of the clone source.
Shift-drag to position
paint stroke in relation
to clone source.
