Compositing fog in After Effects is surprisingly easy. Just follow these steps!

When it comes to creating fog in After Effects, you actually have a lot of options. Most people prefer to use fractal noise, but I find these methods to be lacking. In my experience I find more luck using the turbulent displace method. But if you have any other suggestions for how to create fog in After Effects, I’d love to hear about it in the comments below.

What Real Fog Looks Like
