For example, if you wish to simulate a 50mm lens at f/2.0 in |
| 381 |
> |
a scene modeled in meters, then you divide 50mm by 2.0 to get 25mm, |
| 382 |

which corresponds to an effective aperture of 0.025 meters. |
| 383 |

The default aperture is 0, meaning no depth-of-field blurring. |

This option does not currently work with the |

This requirement may be circumvented by substituting the |

using the |

usually a problem, but it is something to keep in mind. |
