3D needs a trained eye. It can't be done by everybody. People who just do 3D just for the sake of commercializing their movie another five or six percent and they don't know really how to do it, they should care how to do it better by bringing other directors and collaborators into their lives to help teach and instruct how you really make a 3D movie because it's not just like putting a new lens on a camera and forgetting it. It takes a lot of very careful consideration. It will change your approach to where you put the cameras. So, 3D isn't for everybody.
