Prepping for a special effects shot using the greenscreen

This is a diagram I made for the film class that we will be teaching. It's a special effects shot that will require some practical elements to be used and shot on location. ie, the crates will be hoisted on a rope and pulled up and filmed from below. Then an artist will match the lighting and composition, and paint a matte of the zeppelin high up, and hopefully, completing the illusion of a grandious shot. The shot is actually for a film being made here. Previously posted. And the film class will be structured around this film shoot. The kids will learn many of the basics of putting together a film, through this experience.
