After Effects Expressions Simplified

I came across this really interesting article on Creative Cow called AFter Effects Expressions Simplified. It explains how to write and use expressions in a way that's easy to follow. It's especially good for our class because the author builds on things we've already learned.  He explains wiggle and also how you can make it even more powerful than it already is. One thing he describes is how to write expressions that are dependent on each other, so you only have to change one to change all of them.

The article says: "Imagine linking multiple layers to one control layer so that you could globally make adjustments to entire compositions with variables and various expression controllers." When we get into more advanced work, this could really come in handy.

He goes through the process step by step so even if you don't know exactly what you're doing, by following his instructions you could still apply it to your animation. Probably the best way to use this information is to follow this article's tips until you understand how to use them by yourself.
