The birth of Avatar (3)

Although the main purpose of HD camera is to provide references for Weta Digital animator, but it also has other uses, this can create a similar movie with real film shooting environment. This helps the director to shoot and design the screen, and helps actors to understand the relationship between them with lens. When Cameron increase in the digital environment, he can not image what the picture will be. Murthan said:” Depending on the position of camera, the way of actors’ acting are different. When the action extend the close-up frame, the traditional way is shooting the motion capture and then add all other cameras. This method would cause a problem, because all the actors do not know when should take close-up and long shot. When shooting close-up vision in motion capture stage, all the cameras are the same. So there is no acting details difference between close-up and long shot.

When the background adjustment are satisfied, Cameron began add cameras. He uses the virtual camera moves in the CG scene. Matt Madden said:” Cameron will be selectively used the camera to shoot the performances are real-time virtual camera output will be allocated to Avid, the editor will combine all the shots together. When upload the new wcene, Cameron sometimes sit near the editor, and see the editing work, and waiting for the next scene loading. After loaded all the scene, if  he feel the previous shots are good, he will prepare for next shot.” After recisely cut a good camera lens, we regards it as “template”. We hand the template to Weta Digital. Nolan Murtha said:” In fact, the shots we give Weta Digital is rough, but with the complete special effects.”But what in the final movie that will included in these shots.

When create the Avatar model, we added more features to make sure people recognize the actor who plays them. In all Avatar, Grace’s avatar is the hardest sculpture, it is the mixture of The Na'vi and youth Sigourney Weaver, that can comply with the story, because Grace’s Avatar is cultivate out 18 years ago. In order to follow the age of Sigourney Weaver, Stan Winston studio input Zbrush (Alien 3), and use these pictures to create the characteristics of Grace’s Avatar. Jim Cameron explained: . " Na'vi has a wide , like a lion 's nose , like the middle of a brick face, high cheekbones. All of these features are matched with Sam Winthington’s face. In some places it is suitable Sigourney face, she also has high cheekbones and angular chin but her nose narrow high. We tried to add Na'vi wide nose to her face , but it do not like her. You can no longer recognize she is Sigourney Weaver. So we must communicate with John and his team many times, they are great and they have many years of experience in make-up, they know what to do, how to make the different length and width nose of Avatar Grace. We used Sgourney nose to create Grace Avatar, this approach also produced good results , because the role still have big eyes and other features .
