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 set at 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. Settings shown are 0 (top) and 12 (bottom).
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.
The How Often slider controls the period between random offsets.
Normally, when you make a brush stroke, the paper grain is fixed. Strokes repeated
over an area bring out the same grain. The Random Brush Stroke Grain option
randomly moves the paper grain for each dab of each stroke.
