Procedures
To use depth of field for a Camera view:
1 On the camera’s Parameters rollout, in the Multi-Pass Effect group, turn
on Enable and choose Depth Of Field (mental ray).
2 Set the camera’s target distance to the range at which you want objects
to be clearly in focus.
For a Target camera, you can select the camera’s target object and move
it. For a Free camera, you adjust the Target Distance on the Parameters
rollout.
3 On the Camera’s Depth Of Field rollout, decrease the f-Stop value to
narrow the depth of field, or increase the f-Stop value to broaden the
depth of field.
You might need to experiment with f-Stop values to get the effect you
want.
4 Render the scene.
To use depth of field for a Perspective view:
1 On the Render Scene dialog, go to the Renderer panel > Camera Effects
rollout, and in the Depth Of Field (Perspective Views Only) group, turn
on Enable.
2 Set the Focus Plane distance to the range at which you want objects to
be clearly in focus.
3 Decrease the f-Stop value to narrow the depth of field, or increase the
f-Stop value to broaden the depth of field.
You might need to experiment with f-Stop values to get the effect you
want. If you have trouble getting good results with f-Stop, use the
drop-down list to change the method to In Focus Limits, then adjust the
Near and Far values to enclose the region of the scene you want to be
clearly in focus.
4 Render the scene.
To use motion blur:
1 Select each object you want to be blurred by motion, right-click and
choose Properties, then on the Object Properties dialog > General panel,
