step nine: Before we wrap up erasing,<br />
two quick things: (1) as with the<br />
brush, you have complete control over<br />
how your Erase brush works in the<br />
very bottom section of the Adjustment<br />
Brush panel. Click on the word Erase (as<br />
shown here) and it displays the settings<br />
for the Erase brush. You can choose the<br />
Size, Feather (how soft the edges are),<br />
Flow (whether it paints a solid stroke at<br />
100% opacity or whether you want it to<br />
build up as you paint), and you can turn<br />
on/off Auto Mask (we’ll talk about that<br />
next). (2) You have two regular brushes<br />
to choose from, as well, called “A”<br />
and “B,” and you can choose their settings.<br />
I usually make my “A” brush have<br />
a soft edge and my “B” brush have a<br />
hard edge (I lower the Feather amount<br />
to 0), so if I run into a situation where<br />
I’m painting along a wall or other area<br />
where a soft edge looks weird, I can<br />
toggle over to my “B” brush using the<br />
Backslash (/) key on my keyboard.<br />

step ten: I’m going to switch to a<br />
new image for just a moment to talk<br />
about Auto Mask (you turn this on/off<br />
near the bottom of the panel). When it’s<br />
on, it kind of senses where the edges of<br />
things are and keeps you from accidentally<br />
painting where you don’t want to.<br />
Take a look at the image on top, here.<br />
I want to darken the background, but<br />
when I paint on it near the guard’s arm,<br />
it also paints over his arm. However, look<br />
at the image at the bottom. When I turn<br />
Auto Mask on, it senses the edge and<br />
lets me paint over the background next<br />
to his arm without spilling over onto it<br />
(pretty amazing!). The trick is knowing<br />
how it works: You see that little + (plus<br />
sign) in the center of the brush? That<br />
determines what gets painted, and any<br />
area that + travels over gets painted.<br />
So, as long as that + doesn’t go over his<br />
arm, it won’t paint over it, even if the<br />
outer rim of the brush extends way over<br />
onto his arm (as shown here). As long as<br />
you keep that off the arm, it leaves that<br />
area alone.
