VideoCopilot.net has an excellent flash-video tutorial explaining how to create a depth of field rack-focus effect using After Effects.  The results are impressive and the host Andrew Kramer goes step by step through the process.  The quality of this video tutorial just blows me away as I feel like Andrew has taken control of my mouse on my own computer.  The resolution of this video is huge for the web, as the video barely fits in my browser window.  For those of you who can't fit the whole video in your browser window remember F11 goes to fullscreen mode in Firefox and IE.  VideoCopilot.net has a free tutorial section which you should check out as well with 14 other high-quality videos for your After Effects consumption.
