CHAPTER 6 Secondaries with the Pros 179

“Now, what I’m going to do is an isolation appearance. This is some-
thing I like to do.” Pepperman creates a custom user shape for the next
vignette, defi ning one of the buildings. “What I’m doing is, I’m brighten-
ing the building to give it the appearance that the lights are on.” Pepper-
man creates this illusion by raising the highlights and crushing the blacks
inside the vignette. “I’m going to make sure that the blacks are deep, so it
doesn’t look like it’s got a spotlight on it. And the midrange might even

help that. Now, that looks pretty good. Now I’m going to soften it. So I
like that.” See Fig. 6-21.

As his next step in the correction, Pepperman plans to bring up the
blacks on the building to the left and raise the highlights. “I’m going to use
the trackballs to clean up the blue and now I’ll soften it.” See Figure 6-22.
“And then I just want to do one more thing.” Pepperman creates a
custom shape in the middle of the frame and darkens it. “Now it doesn’t
look like it’s darker on the edges. You’ve got a darker feel in the middle too.”
See Figure 6-23.

“Now if I really wanted to, I could isolate the pumpkins and bring
them up. I don’t like the way they clip. I would brighten them back up
to where they’re clipping. Like they would in real life. Because when it’s
clipped like, that but it’s low, it just doesn’t look right. So if I brighten
the pumpkins up, this picture would say day-for-night much better. It
would simulate it much better.” As he blows out the pumpkin lights, the
shot looks much more realistic as day-for-night. “But you can start to see
the illumination or the halo around the building, so we need to tighten
that up.” See Figure 6-24.
