Predefined mark making tools within graphics applications address initial or final stages of a stroke whilst jitter addresses the intervening section of the stroke. Whilst this allows a brush stroke to be simulated as having increasing pressure initially, pressure variability during the stroke, and ending with decreasing pressure this approach does not reflect or mimic the artist's reality. This reality is that an artist applying multiple strokes of a medium, e.g. watercolour, pastels, oils, etc., with an applicator, e.g. a brush, pen, airbrush, marker, sponge or a knife, to a canvas where brush marks may accumulate. Prior art mark making tools and software do not account for aspects of opacity, grain (of the underlying canvas), and blending (of the multiple strokes). Accordingly, there are provided controls with respect mark making tools that address these aspects providing the digital artist with increased control, increased reproducibility, and incorporation of real world effects.
