Agree with you. I was merely putting up some quick examples of the limitations of computer modeling. My point was that PP is not necessarily able to produce any effect at all and that certain effects that are possible would be prohibitively expensive in time or other resources.Personally, I think that art is strongly influenced by the tools used. It doesn't make much sense trying to mimick oil painting with a digital camera or postprocessing. Innovative art is the one that takes full advantage if the new tools, not the one that tries to mimick the past.
The idea being that grabbing a certain lens, for instance, may immediately give an effect that would take enormous effort to delicate.
