The other setting, Brightness, tries to literally equalize, making
most luminance values exactly equal (Fig. 6.65).
The Exposure Effect
The Exposure effect is another luminance correcting effect, like
Curves or Levels. And, although you can use the Exposure effect
in projects that are 8 or 16 bits per channel, it was created for the
purpose of adjusting the exposure of footage that is 32 bits per
If you'd like to follow along, I've created the Exposure.aep proj-
ect in the Chapter 6 folder of the exercise fi les. This contains a
raw camera image that is 16 bits per channel (you can tell this by
selecting the image in the Project panel and seeing Trillions of
Colors at the top), in a project that is 16 bits per channel. That
might seem like useless information now, but it will be important
soon, so just remember this (Fig. 6.66).
Apply the Exposure effect to this image. There are two ways
to adjust an image with this effect—by adjusting the luminance
of the entire image or by adjusting the luminance of each color
channel individually. You choose the type of adjustments you'd
like to make by choosing either Master or Individual Channels
from the Channels drop down at the top of the Exposure effect
in the Effect Controls panel. When Master is selected, you can
