Join John Derry for an in-depth discussion in this video Adding 3D appearance to strokes, part of Photoshop CS5: Painting with the Mixer Brush.
The appearance of grain or texture within painted strokes is but one visual cue…that the brush is painting on a surface.…Another visual cue is the result of highlight and shadowing on a 3D surface.…In this video, I'll show you how to easily introduce apparent surface sliding…to your brushstrokes.…Now, the basic trick behind this is taking advantage of layers and one of the…layer effects that we can apply.…And if I double-click on my layer, this brings up my Layer Style panel.…
And I'm going to select Bevel and Emboss.…And I'm also going to check Contour.…Now, one of the things about the way this works,…you have to first set this up to look like something before you can paint…strokes, but it's most likely that you're wanting to make adjustments to that.…Let's just take the default settings here.…And on this layer, I'll start to paint.…And you can see now that it looks like these strokes have highlights and shadows.…If I turn this on and off, you can see the difference between what it looks…like without and with.…

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.
