To set Jitter:
1 On the Stroke Designer page of
the Brush Creator, click Random.
2 Move the Jitter slider to the left to
decrease deviation from the stroke
path. Move it right to increase
deviation from the stroke path.
Clone Location Variability
Both Clone Location sliders work
with brushes of the Cloning method.
The Variability control lets you
randomly offset the location where the
clone brush samples the source.
When Variability is zero, the pixels of
the source and destination images
correspond precisely—using a cover
brush at full Opacity (and no Grain)
simply re-creates the source image.
The Variability slider controls the offset of the
clone based on the location of the source
image.Top=0, bottom=12.
Introducing a degree of randomness
disturbs the pixel-to-pixel
correspondence. The resultant
variations in the image distance the
clone from its photographic source,
which can contribute to a Natural-
Media appearance.
To set clone location variability:
1 On the Stroke Designer page of
the Brush Creator, click Random.
2 Move the Clone Location
Variability slider to the right to
increase the range (distance) the
sample can be offset. Move it left to
limit offset, causing source and
destination images to correspond
more precisely.
Note
•
Clone location sliders do not have an
effect when Clone Color is checked in the
Colors palette. They have an effect only
when a Clone method is in use.
How Often
The How Often slider controls the
period between random offsets.
To set the period between
random offsets:
1 On the Stroke Designer page of
the Brush Creator, click Random.
2 Move the slider to the left to cause
a greater number of samples to be
offset.
This gives the clone image a
rough, distorted look.
3 Move the How Often slider right
to increase the period, causing
samples to be offset less frequently.
This keeps the clone image more
coherent.
