After Effects Rack Focus: tutorial and preset

Michael Eggert of PixelphileTV posted a tutorial and free preset in After Effects Rack Focus (via Lester Banks):

"We take a look at how to add a digital rack focus to any existing footage. This will add production value to shots that were made on video cameras that don't have a shallow depth of field. You will also learn how to make your own custom presets.

iRack 1.0 is a Rack Focus preset for After Effects CS3/CS4/CS5. With this preset you can add the look of a professional focus pull to any existing footage."
