Once
            you've selected a camera, you can set the properties for each camera
            in your scene.
         
         To set a camera's properties:
         
         
            - In the Schematic view, select the Reaction
               node.
            
 
            - Select the Cameras tab.
            
 
            - From the Cameras list, select a camera.
            
 
            - In the Cameras tab, you can set the properties
               for the selected camera.

                                 - Perspective (default) This
                                    projection simulates a real physical camera.

                                    this projection, all camera rays are parallel, and objects do not
                                    appear to change size as they change distance from the camera. Field
                                    of view settings and depth of field settings available from the
                                    Render tab have no effect with this projection.

                           | Focal Length | 
                           Sets the distance for the camera's focal point. As the
                              focal distance increases, the field of view decreases, and vice
                              versa.

                           | Near Plane | 
                           Sets the minimum viewable distance from the camera. By
                              default, the near clipping plane is close to the camera. Setting
                              the near plane farther back will hide objects very close to the
                              camera.

                           | Far Plane | 
                           Sets the maximum distance from the camera. By default,
                              the far clipping plane is very far away, so that you can see the
                              entire scene. Setting the far plane closer to the camera will hide
                              objects farther away.

                           | Time Dilation | 
                           Modifies the motion blur that affects layers animated
                              in the scene. You can give the layer the appearance of moving at
                              a different speed than is set for Motion Blur in the Render tab.

                              or smaller in the frame.

                           The input stream selector controls which streams of the
                              Reaction sources are used when rendering through the given camera.
                              You can specify an explicit stream index (Manual mode) or let the ordering
                              of the camera in the camera list control the selection of the stream
                              (Match Out).

                                    format of the film gate.
                                 
 
                               
                              
                                 - Horizontal/Vertical Aperture The
                                    height and width of the camera's aperture or film back, measured
                                    in inches. The Camera Aperture attribute determines the relationship
                                    between the Focal Length attribute and the Angle of View attribute.
                                    The default values are 1.417 and 0.945. 
                                 
 
                               
                              
                                 - Film Aspect Ratio
                                    When the aspect ratio of the film is modified, the horizontal camera
                                    aperture is modified. X = Y multiplied by the aspect ratio. The
                                    ratio of the camera aperture width divided by the camera aperture
                                    height. When changed, it dynamically adjusts the camera aperture width.
                                 
 
                               
                              
                                 - Lens Squeeze RatioThe
                                    amount the camera's lens compresses the image horizontally. Most
                                    cameras do not compress the image they record, and their Lens Squeeze
                                    Ratio is 1. Some cameras (for example, anamorphic cameras), however, compress
                                    the image horizontally to record a large aspect ratio (wide) image
                                    onto a square area on film. The default value is 1. 
                                 
 
                               
                              
                                 - Fit Resolution Gate Controls
                                    the size of the resolution gate relative to the film gate. If the
                                    resolution gate and the film gate have the same aspect ratio, then
                                    the Film Fit setting has no effect. 
                                 
 
                               
                              
                                 - Film Fit Offset Offsets
                                    the resolution gate relative to the film gate either vertically
                                    (if Film Fit is Horizontal) or horizontally (if Film Fit is Vertical).
                                    Film Fit Offset has no effect if Film Fit is Fill or Overscan. Film
                                    Fit Offset is measured in inches. The default setting is 0. 
                                 
 
                               
                              
                                 - X & Y Film Offset Vertically
                                    and horizontally offsets the resolution gate and the film gate relative
                                    to the scene. Changing the X and Y Film Offset produces a two-dimensional
                                    track. Film Offset is measured in inches. The default setting is 0.
