FinalRender is shipped with its own default Depth-Of-Field algorithm.

Using Depth-Of-Field with FinalRender is really easy. Next we’re going to explain how to use it.
In order to do so, we must have a camera in the scene. It IS really indispensable. First thing we’re going to do is creating a scene like the one below.

You can light the scene the way you prefer. In our case we’re using Global Illumination, as we’ve explained in other tutorials, to try to have a shocking final image.

Well, let’s configure the camera blur.

Open FinalRender Globals window, and go to the CAMERA EFFECT & ANTIALIASING tab.

Inside this tab we activate Depth-Of-Field (DOF) check box.
Well, Depth-Of-Field is activated by now. If we render the scene at this moment, we would have something like the image below.

As you can see, the result is not good enough. Blur is too rough, and quality is not acceptable.
We’re gonna change the parameters so the objets which are closer to the camera appear clearer, and to improve the general quality.

Increase MIN SAMPLES value to 40 to improve quality, and to see everything without so much grain.
And we decrease APERTURE WIDTH value so the closer objects don’t seem so blurred.

That’s all!!! We get a clear image with a smooth blur as you can see in image.
As far as we’ve seen, FinalRender’s Depth-Of-Field isn’t complicated at all.
