Join John Derry for an in-depth discussion in this video Using the Preset Brush Behavior menu, part of Photoshop CS5: Painting with the Mixer Brush.
There are some more or less universal brush behaviors that are instantly…available via the Mixer Brush Property bar's Preset Brush Behavior dropdown menu.…This menu provides first-time users with some basic brush styles to encourage…working with the Mixer brush.…In this video, we'll take a look at these presets.…So when we're in the Mixer brush, the Property bar is updated to show controls…associated with the Mixer brush, and we'll see right here, we have a set of…predefined behaviors that are available.…
For example, if I select Dry - well, okay.…I get a brush that acts like it's dry.…If we select a Moist brush - okay, I can see where this name comes from.…It's kind of moist.…If we go to Very Wet, for example, well, I'm not really seeing what the…difference is, and that, for me, is a little bit of a problem with these preset behaviors.…Having looked at them, I think what happened was these were designed very much…by numeric settings, without regard for exactly what it was going to do…visually, and as a result, these brush names don't necessarily seem to mean much.…

Q: What factors affect how well the mixer brushes in Photoshop perform? Does document size (i.e. 72dpi vs. 240dpi) affect the performance of the brushes? How can I maximize brush performance?
A: The recordings for this tutorial were generally done at a standard screen resolution, but a real-world situation will often require higher resolutions. For example, offset printing generally dictates files at 300ppi (pixels per inch). Inkjet printing is often discussed in terms of 240ppi. For web-based viewing, imagery at 72ppi is considered acceptable. You can easily determine the pixel resolution of an image by multiplying the size in inches by the above ppi (pixels per inch) factors.
Let's use a typical real-world size as an example: 20" X 24". This is a common photographic print and frame size.
72ppi = 1440p X 1728p = 2,488,320 pixels
150ppi = 3000p X 3600p = 10,800,000 pixels
300ppi = 6000p X 7200p = 43,200,000 pixels
Note that each of these resolution factors quadruples the total pixel count.
It is the amount of pixels being manipulated that dictates both application and brush performance. With this in mind, we can state that performance decreases as image pixel size increases. There are three primary factors that affect an application's ability to handle large pixel-based manipulation.
