Grey Scale Gorilla does a tutorial on Camera Mapping/Projection.

“In part one of this tutorial, I show you how to set up a camera projected scene in Cinema 4D using a photograph. Then we animate the letters using Mograph 2 and light the scene by using a combonation of Global Illumination and Ambient Occlusion.”

“In part two, I show you how to set up your scene to render for compositing. We set alpha passes, depth of field passes, AO and GI passes. Then, In After Effects, we composite the scene using curves, colored solids, blurs, Frischluft Lencare, and Red Giant Knoll Light Factory.”
