Join Richard Harrington for an in-depth discussion in this video Adding shadows to a scene with a "shadow catcher", part of After Effects Guru: Tracking and Stabilizing Footage.
…The use of shadows added into a scene can make 3D effects much more believable.…Let's take a look from a commercial shot.…I'll drop this into a new comp.…And, you can see here, as it pushes in, that we have some camera movement.…And, what I'd like to do is put something over the table.…I'll choose to Track the Camera.…And it'll analyze the scene.…This particular angle is a fixed angle of view.…I was shooting with prime lenses, and the camera is on a dolly.…And what I'd like to capture is the movement of the camera pushing towards…the table.…
And then following its tilt up to deal with the action of our actors.…I'll press E to see the effect and in a moment here,…it'll be done with the analysis.…There we go, and now it solves it.…What I'm looking to do is attach a 3D object hovering over the table and…then have it cast some shadows across the scene.…There's my points.…That one looks pretty good actually.…Let's move that so it's right over that runner.…I'll adjust the size a little bit and attach a text layer and a 3D camera.…
