Open the Auto.aep project from the Chapter 6 folder and apply
the Auto Levels effect to the beluga EFFECT layer. Notice how the
results are similar to what we saw with the Auto Color effect—the
image is brightened, and the color cast is neutralized (Fig. 6.4).
Figure 6.4 The original (left)
and the layer with Auto Levels
Although these results look similar to those we saw with Auto
Color, there is a difference worth mentioning. The Auto Levels
effect actually did a better job at removing the color cast than
Auto Color did.
To compare all three results, duplicate the beluga EFFECT
layer. On the new duplicate (beluga EFFECT 2), delete the Auto
Levels effect, and apply the Auto Color effect in its stead. Finally,
take the Transition Completion value of the Linear Wipe effect on
the beluga EFFECT 2 layer to 75%.
Hopefully, you can see the subtle difference in print, if not, try
this on your own. There is a subtle—but real—difference between
the effects produced by Auto Levels and Auto Color. The center
portion of Fig. 6.5 has the most neutral beluga whale tones, which
is because of the Auto Levels effect.
The Brightness & Contrast Effect
The Brightness & Contrast effect is yet another option also
found in Photoshop. The difference is that Adobe revamped
the Brightness & Contrast adjustment for Photoshop CS3.
Unfortunately, the After Effects version of Brightness & Contrast
is still the old, terrible version, at least when it comes to light-
ening images. Even though I recommend eschewing this effect
