An Erodible tip is internally built on 3D representations of shapes common to various forms of dry media (chalk, pencil, oil pastel, etc.). Using the brush tip can be adjusted to erode (think sanding paper applied to a soft wood). As the tip is virtually rubbed via brushstrokes against the virtual surface, the shape of the tip is planed down. Custom tip shapes can be precisely shaped and added to the tip shape library.

And if you look at these, they suspiciously look like…mediums, like pencils and chalk, and candy crayon…and oil pastels and charcoal.…So, these tips are designed…to emulate exactly those mediums.…And the idea behind them is,…if you look at the square chalk for example,…it's just a perfect square block.…However, as an erodible tip,…as I start to use this, it'll start to actually wear away…at those perfect points on the edges of the corners…and start to wear down the tip itself.…
And, that's what the real…
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.
