If lighting levels are not set up adequately, or some parts of
the image are indistinct (eg., h a i r stran ds), break-through of blue
may occur. Some touching up of the stencil may be necessa ry.
This PRESET lets you clean u p and erase the stencil. Firstly,
move HORIZONTAL PAN to mid position (to stop slide). Now,
just draw wherever stencil needs it. Turn
DRAW
LOCK off to
assist in positioning cursor before dra wing, then press DRAW for
temporary drawing. Use the smallest
Brush s h

for fine detail.
PAN and ZOOM sliders can facilitate stencil clea n u p too. Also
try the
Stencil Draw/Erase
selector in Paint Menu
