THE COLOR CORRECTION
EFFECTS
The Color Correction effect category contains more effects
than any other single category in all of After Effects—26, to be
exact. While that isn't really an indicator of importance, it just so
happens that these effects might be the most important in After
Effects. I say that because all workfl ows use color, and, therefore,
can utilize color tools. The compositor might never need The
Fractal Noise effect. The text animator may never fi nd a use for
the Color Difference Key effect. But, they both still use color, and
will more than likely need to use tools for adjusting color often.
The effects in this category change colors, remove colors, iso-
late colors, colorize footage, bring colors into compliance with a
video standard, and almost any other color-related task you can
think of.
You might be wondering—why are there so many color adjust-
ment effects? Are there really 26 different things you can do with
color? That's a valid question. And actually, many of these color
correction effects perform very similar functions, with differ-
ent ways to do things. If you had footage of a fi re that looked red,
and you wanted to make it more orange, you could use Hue/
Saturation, or Color Balance, Colorama, or even Levels or Curves.
All of these effects are very powerful and would do a comparable
job. The difference is mostly in the way that they are used. The
task is to fi nd color correction tools that allow you to adjust col-
ors in ways that make sense to you.
One of the excellent benefi ts of this category of effects is
that you'll see many familiar friends here if you're familiar with
Photoshop, color and luminance adjustment tools like Color
Balance, Channel Mixer, Levels, Curves, Shadow/Highlight, Hue/
Saturation, and several more, which are in both Photoshop and
After Effects. For the most part, these are powerful, intuitive tools,
and are the foremost reasons that Photoshop users fi nd it so easy
to learn After Effects.
