【插件介绍】颜色偏移插件 EFX Chromatic Aberration 可以增加或者去除色彩偏移效果，可选择 RGB 各个通道的随意偏移，效果相当于 Looks 插件里 Chromatic Aberration 选项的控制，使用于WIN版 AE软件。

This plugin lets you apply (or remove) the chromatic aberration effect to a layer.

This is a known workflow of separating a comp into Red, Green and  Blue channels, scaling one of them and recombining the channels, wrapped into a single effect.

The process of adding chromatic aberration is pretty straight forward if you do it to a single image.

If you try adding it to a layer with an alpha channel, that you later want to composite over a background image, you’ll get into some trouble.

In the tutorial you can see different approaches to the problem, and how the plugin helps you in each one of them.
