You know this thread subject reminds me of something I was ruminating about to myself a few days ago

This is just my opinion but I think the way human eye sight processes
Data  is in a decidedly analog& 2D Fashion thus the human brain is programmed to receive analog images.

Similar to Pumeco's experience I was once a render engine junkie
but now as incredible as it may sound I think imaging technology in general
is now EXCEEDING the human brains actual needs for image data.

Have you ever seen one of those "cutting edge"
4K TV's playing a big VFX movie like "transformers" in 3D??
perhaps its just me but I found the effect jarring and a distraction
and too "clean"

But getting back to our renderings
one of the things that do not look right in CG is when things are too
Perfect this is why a modeling program has an edge bevel.

I find it ironic that a companies like weta digital , ILM etc, have developed such amazing technology that allows us to by pass film altogether
while seamlessly inserting those digital characters ,

 only to have the guys in post production
"Dirty up" the final shot up by adding Digital "Film Grain" to simulate
Classic Analog film stock to make it look more "real".
