Join Mark Christiansen for an in-depth discussion in this video Rack focus with a 3D-generated depth map, part of After Effects Compositing: 2 Matching Foreground to Background.
…Now that we've looked at the fundamentals behind…using a depth map like this one to add…shallow depth of field to a 3D object such…as this, let's create the actual rack focus shot.…Now, it's a little bit more complicated in this…particular scene than just simply key framing the focal distance.…But that is where we'll start.…So here at the beginning, I'll just set this to 0%.…Go to the end.…And I'll rack focus forward to 100%.…Instantly you can see a problem.…
The focal map isn't fitting the board.…The reason for that, is a phenomenon…that exists in this scene called lens breathing.…If I just solo the plate you can see this in action so,…see the slight zoom that's happening between the beginning and end of the shot.…This is a natural byproduct of a heavy rack focus.…I've accounted for it in the foreground by parenting all…the layers associated with the board to this scale null.…So this goes down to 97, from 100.…
