Another one of Photoshop's brushes is the paintbrush, and that's this icon right here. This actually has another brush associated with it. If you press and hold down, you can also choose to use the pencil tool. But for now I want to talk about the paintbrush. The parameters for the paintbrush are very much the same as the airbrush, but instead of pressure, you have opacity. And this works very much the same way as pressure. We do have one other option here, and that's to choose to use wet edges and I will show you how that works. First I'll turn off my wet edges and make a mark here, and I'll lighten up on this so you can see how this looks. And now I'll enable wet edges - and notice the effect. What it does is you get a bit of a darker build-up as if you were using an actual watercolor type of brush. I have some interesting parameters that I can enable. By clicking on this icon over here, it brings up the brush dynamics box. And as I mentioned, if you have a stylus attached to your computer, you can take advantage of some of these. But even if you don't have a stylus attached, you can take advantage of some of these dynamics. I want to show you how these work. Obviously if 'off' is the currently selected item, then they don't change from whatever your settings are in the Options palette. I can choose to fade the size, and it asks you how many steps you want to fade, whatever option you are choosing to fade. In this case it's the size of my brush. I'll type in 20. And now I will make a mark and notice how quickly it fades the size. Fades from the actual brush size down to nothing. So let's change that value to 60 steps, and I will make a long mark, and you can see how that works. Similarly I could choose to fade the opacity, and you can see how it goes from 100% and fades to 0. If I make it also choose to fade the color. And what this does is it fades the foreground to background color in 60 steps. So I'm going to pick a different background color, so we can see how obvious that is. And notice that it transitions from this light blue to green. All these options can be controlled using your pressure sensitive stylus if you have one attached. Another tool I can choose to use is the pencil tool. And the pencil tool will leave non anti-aliased marks. So it creates (a) very hard-edged marks. And if you look at our brushes notice that they have all changed in nature to be non anti-aliased. So there is no transitional area if you choose a brush - they're very hard edged. And if we zoom in to this area, this is the difference between non anti-aliased, the pencil tool and an anti-alias brush. See how there are a few pixels on the edge of the anti-alias brush, which transitions from the solid color to some intermixed colors, and finally stop to background color of the red apple. But if you use a non anti-aliased brush there are no transitional pixels. It's just very hard edged, and when you zoom in you can see it's conforming to the grid of the image resolution. The Auto Erase feature of the pencil tool is a very interesting twist on a painting tool. What it does is it paints with the background color, if you begin painting on an area which has the foreground color already painted in it. So to demonstrate this, I will come over to an area that has nothing painted in it, and began painting. And you can see as you would suspect, since I've picked my foreground color, it's painting with that color. But now if I start to paint on this area, the Auto Erase tool will switch to the background color instead. So that's called Auto Erase.
