The 3DVX3 does not appear to have adjustments for interoccular spacing or convergence. How can I control the 3D parameters of a shot?
There are many different approaches to shooting 3D. Some like to have the option to vary the distance between left and right eye camera views. Some like to have the camera’s viewpoints cross, or converge on an object of interest. 21st Century 3D has a slightly different philosophy of shooting 3D. Since our own eyes never move farther apart or closer together, but still see very realistic 3D images in the real world, we believe that it is possible to create great looking, comfortably viewable 3D images without varying the distance between cameras. While it is true that extremely long focal lengths can benefit from wider camera separations, we choose to avoid these type of shots. The telephoto lens has a flattening effect that can hurt the 3D image and create an unusual effect. As for converging on objects, this can also introduce distortions that we prefer to avoid. The same effect is achieved with the 3DVX3 by offsetting the image axes in post production. This allows for precisely sett
