The Photoshop 7 Paint Engine, Part 2

Dual brush dynamics By Dave Nagel
Last time around in our exploration of the Photoshop Paint Engine, we looked at methods for creating custom brush tip shapes using paint tools and filters. Now we'll begin a new section covering paint brush dynamics, a set of features that help to make the Paint Engine in Photoshop 7 far superior to anything seen in Photoshop previously for creating custom brushes for emulating "natural" media (as if chemical-based paints were any more natural than digital paint tools).

Why?

Certainly, you can create custom brush tip shapes in Photoshop 6. But what happens when you apply them to a canvas? No mater what shape your tip, the stokes come out solid and flat except on the leading edges. There's no texture and certainly no sense of interacting with the canvas beyond drawing the shape of the stroke. So then to create nothing more than the "look" of texture, you turn to filters and become even further removed from the process, at which point you might as well give up on painting. It's all about the process.

But the dynamics in the Photoshop 7 Paint Engine allow you to move beyond this limit.


We'll begin with a brush tip shape designed to look like a small wedge of charcoal. If you'd not care to design your own to follow along with this tutorial, feel free to download mine here: http://images.digitalmedianet.com/2002/10_oct/tutorials/pspainteng2021030/NagelCharcoalTip.abr.

Now, if you look at the example below, you'll see that applying the brush in a single dab (the white dot in the middle) does indeed reveal some of the texture detail of the brush.



However, when you draw a stroke with it, the texture is lost, except along the leading edges.



There are several things you can do about this problem using dynamics. But there's only one thing you can do that doesn't alter the texture, color or shape of your brush tip: the Dual Brush dynamic.

Dual Brush is an option that allows you to intersect a second brush tip shape with your primary brush tip shape. You can use either your current brush in the dual brush mode or any of the presets currently loaded on your system. For purposes of this tutorial, we'll simply be using the same brush tip as the primary and dual brush tips in order to preserve the appearance of the original.

To activate it, simply click on the Dual Brush name in the Brushes palette, and then choose the tip you want to use as the second brush.
