Switching from VRayPhysicalCamera to standard
Typically in most scenes created by using V-Ray renderer, many visualizers use specialized camera called VRayPhysicalCamera. It has many settings that simulate similar real camera settings and therefore it is easy to use in it's own way.
However, it is not always possible and convenient to use the camera of this type in practice. For example in the case when it is necessary to perform an orthogonal visualization from the camera, or to create interactive virtual panorama or use any special plug-in/script. In these cases, more preferable and sometimes the only possible is an use of standard 3ds Max camera.
It is important to know how you can go to a standard camera therefore, even if the scene was originally set up to work with V-Ray Camera. This wouldn't take much efforts...
