This was a challenge for CG Tantra that you need to take the shot, clean the people on the beach, replace the sky, and make an Air France crash! They give the model and texture of the airplane, but I couldn't make on time, because I'm not good with dynamics and I was working on a TV Station that time... So what I really did was tracking the scene, extend the frames of the shot, clean the people, replace the sky, put a Teapot for show that the tracking is working, and show that light setup match the original light of the scene shoted. And I put a girl on the beach for give the excuse that the cameraman was recording the girl in the right moment that the airplane should crash. The girl was shoted in greenscreen.I'm not completly happy with her, because she is a flat plane, and of course because of the camera movement(PAN) she doesn't match perfetly.
