Benjamin Button TED talk

Behind the Benjamin Button movie, the oldness of the main character isn't showed by wearing make up. The movie production group make the actors face totally computer generated, so it looks more real than just putting on make ups. While making the old face of the actor on computer, they used the science method to slowly make the old face, and their goal is to let the actor to control the old face they made on computer. They first take pictures of Brad Pitt, and they try to get every kind of facial expression he can make, and they generated on a computer to make it look older, and then they will attach it on the actor that's acting it. They have this kind of technology which you put reflective marker on your body, and there will be sensors around you to capture the movements that you are doing. To capture the facial expression, they have this special make up, they put it on Brad's face, and he'll stand in front of a special machine that reconstruct someone's face, in this case they make it look older. They got a very good photographer and a good sculpture maker, and first the photographer took a lot of picture of Brad standing under the special machine with the special make up, and there were a lot of facial expression. After that, they started to transpose Brad's face into another model, then they make it look older. Later on, they start shooting, and they make Brad look at the image, and to act out the facial expression of the old man. They also break it into many specific parts, like mouth, eyes, and the head. The background was a important part too, so they put the face into different kind of places. It is a long process to make this man, and it really take a lot of different people and different technology to work it out. The old man's body is act out by other actors, and the face is a computer generated Brad face. I think it's pretty awesome and cool!
