the Wacom art pen can be used to express
rotation with many brush variants and
painter in addition to those found in
the real bristle brush category if
you're using the flat tip into a start
pen that supports 360 degree barrel
rotation you can adjust your brush
strokes based upon the rotation of the
stylus in painter you can change the
expression setting to rotation with the
art pen which supports tilt and pressure
however there is no better way to
achieve full barrel rotation than with a
Wacom art pen I enjoy painting roses yet
I could never quite achieve the subtle
nuances of this shifting petals and the
many directions the rose petals form
until I discovered the art pen and the
ability to achieve that full barrel
rotation which many of the default and
many custom brushes I can now apply
rotation to to achieve just amazingly
beautiful petals so what exactly is
barrel rotation the dot or purl that
appears along the outer circle of the
enhanced brush ghost indicates the pen
rotation so let me show you this so I
have my art pen and I'm using the thick
paint oil pallet knife and I'm going to
reset it because I want to show you how
to get this set up to full barrel
rotation using the expression setting
now the expression setting can be
accessed from many of the different
controls panels within painter such as
opacity grain size
angle and in the airbrush you can choose
the feature and flow impasto liquid ink
and on and on color expression or any or
any of the particles or thick paint
panels also you can choose that
expression setting as well so without
said I want to show you how this brush
behaves without full barrel rotation or
rotation in the expression setting if I
wanted to create say for example a
vertical brushstroke that was very thin
as you follow my brush here you can see
that I'm not able to achieve that it's
very difficult for me to move the brush
to get it to the rotation that I need
there's very little control in that
brush however let's go back now and take
a look at the expression setting under
angle and you'll notice it's set to
bearing but let's set it now to rotation
which enables us to take full advantage
of 360 degree barrel rotation beyond
that let's go ahead and set the angle
range to 360 degrees and we'll set the
step to 4 and that will give us a nice
rotation so let me enlarge this brush so
you can see this as I rotate this brush
the stylus between my index finger and
thumb you can see visually how the brush
is rotating around you just don't get
that with a standard pen this is unique
to the art pen and unique to this
expression 360 degree rotation
so as I begin using this little diagram
here and starting at 12 o'clock say for
example I wanted a thin stroke at the
top so let's go ahead and lay down a
nice thin stroke and you can see that as
I move and rotate the barrel I can go
around this clock and get precise brush
stroke in each area based upon what I'm
looking for now what if I wanted this to
be a wider brush stroke you'll note that
the vertical incline of this brush
creates a very thin stroke and the
horizontal creates a very thick stroke
so it gives me that opportunity to
really play with this brush and get some
nice movement and expression within the
brush let's take a look now at the heavy
textured pallet knife and we'll reset
that to default settings and then take a
look again at the expression with this
brush we'll set the rotation again to
we'll set the expression to rotation and
the angle range to 360 and the step to 4
and again I'll pick up a color here and
notice how as I begin how I can create
this really really nice angle as I move
around
this template now if I want to change
direction I'm going to go back the other
way and you can see how this brush picks
up and creates that beautiful angle so
if I bring this brush down smaller will
go to a darker color in the center and I
want to start building say for example
the rose petals around notice as I turn
my stylus and based upon the direction
of that Pearl I can achieve this
beautiful beautiful rotation and this is
a really great way to start and to
practice with this with rotation when
you're working on a little template such
as this that will help you to visually
see the direction those petals are
moving
again with a standard pen I would not be
able to achieve this kind of rotation in
the brush so whether you're looking for
a very thin brush stroke or a very fat
brushstroke or being able to achieve
full barrel rotation within that brush
stroke the art pen is definitely a
stylus you'll want to discover and use
in painter
so now as I begin to finish this
painting I can take full advantage of
those different difficult angles that
may be present in this particular
composition and with rotation activated
I can easily now create those little
edges that are important and those
additional petals that may I may need to
bring out in the roses and as I do this
you can see how each of those
brushstrokes reacts to the rotation of
the pen and I'm able to get very very
subtle changes to that brushstroke as I
go
so again I hope you see the advantages
of using the art pen to create that full
360 degree rotation that enables you to
get some very very beautiful beautiful
brushwork going in your paintings and to
give you superior control in terms of
the actual placement of that brushstroke
