For ease of identification, custom brushes were defined using numerals. It sets the smallest instance that the brush will produce when Roundness Jitter is activated.Įxamples of the shape dynamics are shown here.
Minimum Roundness: You can constrain the Roundness variations using this slider. Roundness never increases the height beyond that selected with the Diameter or Master Diameter sliders. At 100% jitter, the height of the brush instances will vary between approximately 5% and 100% of the size specified in the Brushes palette. As you increase Roundness Jitter, you add variation. When set to 0%, each instance of the brush has the same width-to-height relationship. Roundness Jitter: The Roundness slider controls variation in the proportion of a brush tip. (You don’t need to change the Angle Jitter from 0%.) Orient the brush tip to the path by changing the Control menu under Angle Jitter to Direction. At a setting of 25%, the orientation of the brush tip with vary from -90 degrees to =90 degrees Remember that, by default, the angle is relative to orientation of the page rather than the path of the stroke – even if you drag a circular stroke, the variation in angle remains relative to the top of the image. The Angle Jitter setting determines the degree of variation. Angle Jitter: With non-round brush tips, the angle of application can be varied. 
Tilt Scale: When the Control pop-up menu is set to Tilt, this slider regulates how much the angle of the stylus will affect the brush stroke. Minimum Diameter: You can constrain the size of the smallest instances using the Minimum Diameter slider. 
In no case will Size Jitter create instances of the brush tip larger than the Diameter selected in Brush Tip Shape or the Master Diameter selected in Brush Presets. At the maximum of 100% variation, instances of the brush tip can be as small as 10% (or smaller) of the diameter that you have set. Size Jitter: This slider determines how much variation there will be in the individual instances of the brush’s tip.
