Photoshop's brush strokes are not continuous. Brush strokes are an illusion created by closely spacing a brush tip shape, thereby overlapping the tip shape close enough that the stroke appears to be continuous. Manipulating the tip shape to create space between the shapes can be a useful technique for creating some types of brushes.

- [Voiceover] Did you know…that Adobe has been fooling us for years,…into believing that Photoshop's brushes…paint continuous strokes of color.…Well, I'm here to tell you that it's a total conspiracy.…I'm going to unmask this fallacy,…once and for all,…right here in this movie.…I'm gonna be working with the hard, round brush.…Let's go ahead and open up the brush panel.…I'm gonna just draw a little bit with it.…What I want you to notice here…are a couple things.…One is,…the default spacing for this brush is 25%.…
But if we get close to this,…you can see these little,…what I call, bumplets…along the edge of this.…That is because,…each one of these,…what are actually individual strokes,…and we can actually prove that…by expanding on the spacing.…You can see there's actually a single dab.…And depending on how it's spaced,…you are going to get…either the illusion of a continuous brush,…or if it's not set low enough,…you're gonna start to see these artifacts.…Now, I suspect that the reason this brush,…which has been in Photoshop forever.…
John begins by going over some important brush tips that many artists are unaware of: bristle, erodible, and airbrush tips. He talks about how to customize the brushes and use them to mimic natural bristle brushes, chalk, and spray paint. He also addresses some global issues such as paint flow and spacing, which can have a dramatic impact on any brush you create.
From there he jumps into some more advanced techniques, such as blending colors, loading brushes with multiple colors, and using Brush Projection. Use these tips together to extend the toolset and maximize your creative freedom in Photoshop.
