EFX Chromatic Aberration插件可以让你增加（或删除）色彩偏移效果，可以选择RGB（红绿蓝）三个通道的偏移。下面包中带教程，大家慢慢看看吧。
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.
