Curves' Two Export File Types
A little known secret about Curves is that it can actually export curve fi les for reuse later. If you click the little disk
icon on the side of the Curves effect in the Effect Controls panel, you'll be prompted to save an ACV fi le. However, you
can also create curves by clicking the pencil icon, and then drawing the curve by hand. Then, when you save the fi le
with the pencil tool you selected, you'll save an AMP fi le. This AMP fi le can be used with the PS Arbitrary Map effect,
discussed later in this chapter. Both ACV and AMP fi les can be loaded back into the Curves effect (in either Photoshop
or After Effects) by clicking the open fi le icon that looks like an open folder on the right side of the Curves effect in the
Effect Controls panel.
The Equalize Effect
If there were a luminance-based communist movement, the
Equalize effect would be its leader. The purpose of the Equalize
effect is to redistribute luminance values across an image, so that
there is a greater balance among all pixels.
Open the Equalize.aep project from the Chapter 6 folder if
you'd like to follow along. This project contains a shot of the
Space Needle in Seattle, Washington (Fig. 6.61).
This image is out of balance, as it was taken as part of an
HDR sequence. Because of this, it has a lowered aperture value
(f-stop), which eliminates the highlights. However, we need to
call in a favor from another tool to really see what the matter is
with the luminance in this image. Apply the Levels effect to see
Figure 6.61 The space needle
comp in the Equalize.aep project.
