Lens Aperture: A cameras lens aperture greatly defines the look its blur. Therefore they offer the possibility to alter the lens apertures form to simulate several kinds of real cameras. This is important if you want to comp cg elements into real footage or just want your cg shot to fit in with the rest. A wide range of apertures can be simulated. The Out of Focus plugin provides the possibility to completely replace the aperture with a custom image. The aperture's form is most apparent in a picture's highlights.

Background distortion: Only available in 'Out of Focus'. When looking through a blurred object the background is distorted due to the blurred object in the foreground. Most of the time this effect is not very apparent.

But slight distortions help adding to the believability of your comp. To experience this effect try holding your finger in front of your eye so that it is out of focus. Now look through the blurred region on whatever is behind. Move your finger around slightly to see the effect better.

This is obvious when you see that the depth buffer can only hold one value per pixel. But the biggest problem is with no doubt the missing information. Depth of Field tries to compensate for missing information but of course there are situations when this is not enough. An example to illustrate the problem is a fence in front of the camera that is so much out of focus that it's hardly noticeable in the resulting image. Now our plugin would have to make up what's behind that fence completely.
