Anyway, the settings I suggest above are for a small-to-medium canvas, 2000 x 2000 pixels. People who try the brush in real life may have to find their own optimum setting for each case. My personal opinion is that the spontaneity of the resulting effect is well worth the trouble.

By the way, thank you for visiting, John! Always a pleasure to have you around.

Nice to see you exploring Velocity…

One bugaboo that relates to the use of Velocity with brushes:

A Velocity-enabled brush is very sensitive regarding the resolution of the image it is applied to. For example, if you find Velocity settings that work well for a screen resolution-sized image, the same settings will not work for a high-resolution image and vice-versa. This is because the velocity with which one draws at screen resolutions will be exaggerated in a high resolution image.

In other words, the velocity at which you draw from one corner to the opposite corner in a small image will be much faster when the same action is done in a high-rez image scaled down to fit the screen. This is because the same action onscreen is actually a much greater distance on the hi-rez image, hence the velocity of the stroke is scaled up.

As a result, a setting that works well at one end of the image resolution scale will not work well at the opposite end of this scale. I’ve created several Velocity-based brushes that I really like, but this behavior (which is not Painter’s fault) means that this class of brush must be hand-tuned to the specific resolution of the image it is being used in.
