Join John Derry for an in-depth discussion in this video Understanding dabs, part of Corel Painter 11: Brushes.
A brush variant's business end is the dab. The dab is what establishes the graphic quality and character of a brush stroke. So they're very important in terms of how brushes are made when the pin touches the canvas. I'm going to show you where we find brush dabs. So we're going to go up to the Window menu and we're going to go down to Brush Controls > General and this will pop- up the entire Brush Control palette, but the one that's really important is General and it's actually located at the top for a reason.
It's almost like a top-down view of the importance of what makes up a brush stroke. So right from the get-go Dab Type is very important and the drop-down menu is how you access all of these various dabs. Now don't be too confounded by the number of dabs you see here. Some of them are actually duplications. For example, Water Color, Liquid media, they're the same dab types. They're just designed for specific media, but we'll be looking at these in-depth throughout the entire title.
To show you exactly what I'm talking about though, I'm going to use an airbrush and I'm just going to do a one dab and you'll see that basically that is an individual hit of the brush on the canvas. If we go to the Size menu, we'll see that there is the actual dab and in the case of airbrushes, these dabs are actually kind of canned within Painter to be various density distributions, like you'll find in an airbrush.
What's happening is the Painter takes this one dab, and I've actually got to kind of jiggle here to make it build up a few times so you'll see it. It takes that dab and spaces them so closely that when you paint, it looks like it's a continuous brush, but actually those are very closely spaced dabs that create the illusion of a complete stroke. Based on these various profiles I'll get a different kind of quality for the way that the dab and its appearance along a stroke path is going to appear.
So Profiles are just specific built-in examples of dabs within Painter and as we'll see later on in the title there are a whole number of various ways to make and create dabs to get that really wide range of character that Painter is known for. The last thing we're going to look at right now is Jitter. Jitter is something that actually controls where this dab appears along a stroke. I'm going to temporarily close these up and go down to the Random palette and you'll see here we have the Jitter slider.
When I turned this up, you'll see now what's happening is I'm still on the same path, but what's happening is those dabs are being randomly thrown off of the center line of the stroke. This is such an important control for many brushes to introduce a different kind of quality into it that this control is actually mirrored up in the Brush Selector bar. So you don't necessarily have to go down into the Brush Control palette to get to this control. You'll find it up here.
In fact, many of the very standard highly used controls within Painter will appear in the Brush Control bar. So Dabs, and Profiles, and Jitter, are all various aspects of how to control where and when a dab happens along a stroke.

Q: In the chapter 9 video "Understanding the Master Brush Library and the User Brush Library,” at the beginning of the video the author states that the demo will be on a Mac but that the Windows file system information will be displayed as well. The Windows path information never appears. What is the correct file information for using this tutorial with Windows?
A: Unfortunately, the Windows portion is indeed missing from the video. Below is the pertinent information.
