Join John Derry for an in-depth discussion in this video Setting texture scale, part of Photoshop CS5: Painting with the Mixer Brush.
The Scale slider is another great tool for controlling and adjusting the…appearance of texture within your strokes. Let's take a look.…I am going to start off by just drawing a little bit with what we have currently.…And one of the things that I don't like about the look of this stroke is that's…a very large stroke for looking like a canvas.…It is canvas, and at the appropriate scale of image, this may look right.…But right now, it just looks too large to my eye.…So I can use the Scale slider to turn this down.…
So I can start to use this to get down to a level of scale that seems…appropriate for showing this onscreen.…Even now, it's still a little high,…so we are going to go ahead and turn this down.…And now what starts to happen here is that it's getting so small, there's…not much separation.…So you need to find that sweet spot. That gets there.…That's starting to look very good.…The other thing we can do here is we can control how we are addressing the depth…of the texture through the Depth control.…

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.
