A dual brush is essentially a brushtip shape masked by a second brushtip shape. This arrangement enables the creation of emergent brushes: dynamic brushtip shapes that constantly evolve as interference patterns being the result of the 2 overlapping brushtip shapes currently in use. A dual brush wins for its capacity to create brush behaviors that would appear to be beyond Photoshop's capabilities.
- [Voiceover] Earlier, we looked at the mixer brushes…ability to sample color imagery…then paint with that sample imagery…using a captured depth shape as a mask.…What if we could use a brush tip…as mask for another brush tip?…Essentially a brush nested in a brush.…Imagine the high degree of dynamic tip change…that would be possible.…Oh don't you just wish?…Hey, guess what?…This is totally possible with the dual brush.…
Let's examine this beast.…So I'm going to start with a very just simple brush.…The round, hard dab.…I'm going to open the brush panel up.…I'm going to go down to dual brush.…And I'm going to take the word text.…And I'm going to have it paint inside this mask.…So think of this, right now this brush…as a normal brush is painting with the current color.…As soon as we turn it into a dual brush,…it is going to merge this shape using it as a mask…to apply whatever secondary brush…we put inside of it so that we'll get…a completely different look.…
I've now selected the word text and let me…be sure that you understand this.…
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.
