Below are various examples of complex structures produced with DOF PRO. The images below are straight output from DOF PRO and have not been edited / processed in any way. Whenever we deal with complex structures and post processing filtering, artefacts are difficult to avoid, mostly due to information which has to be extrapolated as a result of not exisiting in the original image. The quality of the processed image therefore greatly depends on the types algorithms used for extrapolation, as well as the method in producing the image.
One common issue with all DOF postprocessors is that whenever you have a blurred edge in front of something, there is missing information about that image behind the edge which has to be reconstructed somehow. Since this missing information cannot be reliably extrapolated, an alternative is to reduce the artefacts produced by softening the visibly hard edges resulting from the depth map. This can be achieved by applying the same DOF PRO processing to the depth map for use with the image in question. This will effectively minimize and/or eliminate most visible artefacts without having to rely on image extrapolation and/or reconstruction.
All the following mathematical models were created and licensed for use from Jotero. They were textured, lit, rendered and DOF PRO processed by myself for the gallery. All images were rendered with VRay 1.47.03 using 3dsmax 6.0. The Depth Maps were generated using 3dsmax's fog feature with VRay and DOF PRO.

For our final complex structures examples we have an animated sequence of structure #1. This is with considerably high DOF settings yet the processing is handled very well, without any much artefacting. There is some flickering but this is due to the original RGB render where the highlights vary in intensity slightly from frame to frame. Licensed for use from Jotero
