Join John Derry for an in-depth discussion in this video Loading and cleaning the Mixer Brush: Manual or automatic, part of Photoshop CS5: Painting with the Mixer Brush.
Loading and clean your brush affects the behavior of how strokes are applied to the canvas.…You have a choice of whether you want to do this manually or have Photoshop take…care of it for you automatically.…In this movie, we'll take a look at both methods.…Up until now, I've been using these controls both turned on, and we're now going…to talk about what these do.…The Load control loads the brush for you automatically, after each stroke.…And when it's enabled its dark,; when it's disabled it's light.…
The second control is the Clean control.…This cleans your brush after each stroke, and like the first control when it is…disabled, it is white, and when it's enabled it's dark.…Let's take a look at how these work.…Now to start with, when these are both on and I started to paint, each stroke…is always loaded, and each stroke will always clean itself after each stroke is produced.…Now what happens, for example, if I turn off the ability to fill the color well,…each time the stroke is produce?…Well what happens is we don't get anything, but this turns this in to…

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.
