- Blend the outline with the colored layer. To merge the lines
with the original color image, choose the Multiply mode from
the blend mode pop-up menu in the Layers panel. The dirty
filthy result appears in Figure 4-43.
Figure 4-43.- Apply another filter to facilitate cleanup. Naturally, we don’t
want our subject to look like she’s rubbed her face in graph-
ite or succumbed to some dread 21st-century plague, so some
cleanup is in order. We’ll start with the digital equivalent of
a vacuum cleaner, and then we’ll do some hand-scrubbing.
Choose Filter→Blur →Gaussian Blur. In the dialog box that
opens, enter a Radius of 2.0 pixels, and then click OK. The re-
sult doesn’t look any better, but it gives you some gray values
that you can trim with the Levels command. - Adjust the Levels. The Levels command allows you to ad-
just brightness values and is the perfect tool for getting rid
of the gray values we created in the preceding step. Choose
Image→Adjustments→Levels. Increase the first Input Levels
value to 115 to punch the blacks (make them darker), and then
decrease the third value to 140 to drop out the whites, as pic-
tured in Figure 4-44 on the facing page. Click OK to accept the
change. The result is a much cleaner image but not clean enough.
