Field of View Control
The Field of View (FOV) control sphere acts like a zoom lens control. The higher the setting, the wider the field of view for your lens.
Because you are admitting more information into your lens, it will create the illusion that objects are receding from view, or getting smaller. That is not the case. Since you're admitting more information, existing objects necessarily occupy a smaller percentage of space within your field of view.
If you drag the Camera Z control to bring your "receding" objects back up to a larger area in your view, perspective distortion effects appear. This is particularly effective for creating broad, swooping cloud scenes.
When you view the camera in Director's View or one of the Orthogonal Views, you'll be able to see the camera's Field of View displayed as a 3D pyramid that extends from the camera wireframe. The large triangle that extends from the camera's wireframe represents its field of view. As the field of view changes, so does the shape of the triangle.
By default, the camera's field of view projection is visible.
Changing the Field of View only works in Director's or Camera View.
To increase/decrease the Camera's Field of View, drag the Field of View control, which is located to the top right of the Camera Trackball.
