There are good reasons why both the VFX/post production and music production industries have done vast amounts of research into accurately modelling every 'imperfection' that resulted from the pre-digital processes. If you remove all the imperfections, you end up with something that is sterile. Digital production methods are great at producing data in very predictable, reliable ways. But our brains our great at spotting patterns, and they can tell really quickly if something is unchanging and can be ignored. So while the challenge in the analogue world was creating order (a faithfully reproduced signal) from chaos, in the digital world it's flipped. We need to find ways of adding some chaos to make the resulting signal interesting to our brains.
