A camera model that approximates a number of real world physical effects.   
  
This supports all of the traditional prman perspective camera settings including shaped motion blur and bokeh.

Some examples of the effects PxrCamera can do:

Barrel Distortion / Chromatic Aberration / Split Diopter / Tilt-Shift / Vignetting

###   
Standard Parameters

**fov** 

Field of view (FOV) in degrees. For rectangular images this is normally the FOV along the narrower image dimension.  
  
Below is a conversion table for standard prime lenses to their horizontal fov value  
  


| **lens mm** | **Horizontal fov** |
| --- | --- |
| 18mm | 90 |
| 25 | 71.5 |
| 35mm | 54.4 |
| 50mm | 39.6 |
| 85mm | 23.9 |
| 100mm | 20.4 |
| 135mm | 15.2 |

  
Therefore, to mimick a 50mm prime lens with the PxrCamera, you would enter the value of 39.6 in the FOV parameter

**fov** **(end)**

Field of view (FOV) in degrees. Used to motion blur fast zooms. 0.0 means it is the same during the rendering

**F-stop**

Aperture size, controls depth of field blurriness. High values emulate a pinhole camera and depth of field is disabled.

**Focal Length**

The focal length of the camera in scene units measured from the camera lens. High F-stop values disable this.

**Focal Distance**

Distance to the focal plane where objects are in focus, measured in scene units from the camera to the object. High F-stop values disable this.
