After Effects Tutorial - Underwater scene with light rays and bubbles (Deep Thought Pt1)
In the first part of this two-part tute, I'll be showing you how to create a subtle underwater scene, complete with light rays, rising bubbles and a cloudy texture. No plug-ins required, so this can be done out of the box with CS3, CS4 or CS5.
Part 2 will cover using using lens blur with a depth matte, and is coming soon.
