Step Seven:
Now that we've brightened the scooter,
we're going to darken the background, but
we can't just continue dragging sliders
around, because that would just change
the scooter, since it's the only area we've
painted over. To paint over a new area,
and have separate control over it, you'll
need to click the New button (shown
circled here in red). Now, you have to
choose what you want to do with this
new area you're going to paint in. Choose
Exposure from the Effect pop-up menu,
and then drag the Exposure slider to the
left, to darken the area. Again, it doesn't
matter how far you drag the slider to the
left, because you'll change it later. Now
start painting over the background to the
right of the scooter, as shown here, and as
you paint, it darkens that area.
Step Eight:
For painting a large background like this,
here's what I do: I turn off the Auto Mask
checkbox, then I quickly paint in all the
areas in the background that aren't right
up close to the scooter (in other words,
areas where I don't have to worry about ac-
cidentally painting over the scooter). Then,
when it's time to get up close to the edge
of the scooter, I turn the Auto Mask check-
box back on, and paint right up to the edge
of it (as shown here) without darkening it.
The key is to keep the little + (plus sign) in
the center of the brush from crossing over
onto the scooter. That little plus sign deter-
mines which colors to paint over. If it strays
over the blue, it figures its okay to paint
over it, so as long as you keep that off the
blue, it keeps the darkening off it, too.
