Comm 333 Ch. 6-7

Persistant vision, realism and hyper reality are not new concepts in any form of media.  Indeed, the former two ideas are almost a century old or more, with Persistant Vision being originally theorized as a concept in the early 1920's and realism being far older.  Realism in particular can apply to anything from paintings to film, and has just that over the last two hundred years or so.

Realism as we know it today is applied mostly to film.  Programs such as late night talk shows or "live" TV are considered realism because while they may not be filming this program live, i.e. you're not watching it as it happens, they are meant to give the feel that it's all happening now.  Bands playing during such talk shows are made to look as if all their music is live, even though the sounds levels are far too even, and the band in question will probably sound exactly like they have on their album.  Be that as it may, all of these factors come together to make a realistic atmosphere.

Hyper reality comes into play moreso in films, where everything is so gritty and panoramic that everything seems too real, or too perfect.  The frame rates are so smooth that it plays out like our own field of vision (or faster) and "reflects" reality in excruciating detail.

That brings us to the concept of persistent vision.  PV, as we'll call it for now, is the brief (.25 second) after image that is left in our eyes after an image has been viewed.  For film and TV, this means that anything above 12 frames per second will have a sufficient after image to make transitions from one frame to another flow seamlessly.  Since most movies run at around 24+ frames per second, this creates a sense of realism or hyper realism as the case may be,
