Stroke Designer Palettes Random

Computer brush strokes can often be too precise and accurate, unlike when we paint traditionally and our hands flex and the stroke varies. The Random section gives us some controls which will reduce the regularity of the brush strokes. Figure 4.15 shows how the sliders affect the picture from the left.

1 Using Square Chalk, the first is a normal stroke.

2 The Jitter slider is at 2.67, which places brush dabs at random places, the picture is still in register with the original clone source.

3 Clone Variability is set at 34. This control offsets the place from which the clone is taken. Moving the How Often slider changes the source more often.

4 Random Clone Source has been ticked which takes each brush dab from a different part of the original clone but in a totally random manner. The result is a collage of elements from all over the picture.
