The Curves Effect
The Curves effect, also found in Photoshop, is another one
of my go-to effects, and is generally one of the more common
effects out there. The most popular use for Curves is adjusting
luminance, but you can also adjust the values of each color chan-
nel independently if you want to use Curves as a color adjust-
Curves is often compared to another luminance correcting
Photoshop favorite—the Levels effect. We'll talk in detail about
Levels a little later in this chapter. For now, all you need to know
is the difference between Levels and Curves. In essence, Levels
allows you to adjust three components—shadows, midtones,
and highlights. Curves, on the other hand, gives you individual
control of up to 256 different tones. As you can imagine, with all
of that extra control also comes an extra degree of challenge in
learning this effect. But, once you understand what's going on,
you'll fi nd yourself turning to Curves all the time.
I've created a project that we'll use for both Levels and Curves
so that you can use them on the same fi les to get a better idea
of how to create the same results with the two effects. Open the
Levels and Curves.aep project from the Chapter 6 folder of the
exercise fi les. First, we'll start with the fi reworks comp, which is in
desperate need of some Curves love (Fig. 6.53).
In this otherwise cool photo, the fi reworks aren't quite bright
enough as this shot was taken when it wasn't late enough at night.
Additionally, because of the time of the shot, the night sky isn't quite
dark enough. Now, apply the Curves effect to this layer. In the Effect
Controls panel, you'll see the baffl ing Curves interface (Fig. 6.54).
