Join John Derry for an in-depth discussion in this video Quickly loading and cleaning the Mixer Brush with keyboard shortcuts, part of Photoshop CS5: Painting with the Mixer Brush.
Just like its natural media counterpart, you need to be able to quickly service…your brush by both cleaning it and loading it with color.…The Mixer brush has some shortcuts for performing these actions,…but Adobe does not assign these shortcuts by default.…In this video, we'll learn how to assign shortcuts, as well as add them to the…Wacom control tablet surface.…I'm going to begin by showing you an example of what I'm talking about, and I'm…using the Blunt-Round Dirty brush from the Tool Preset library that is included…in the exercise files.…
And let's just put a bit of color onto the screen.…Now, when I start to paint with this brush, what happens is whatever is…underneath the brush at the end of a stroke, gets contaminated into the next…stroke that's produced.…So, what will happen is you'll get a natural media type effect of paining wet in wet.…Color on the brush gets contaminated by what it finds underneath of it, and that…can be a useful technique.…The reason it happens in a dirty brush is because neither the Auto Load or…

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.
