Persistence of Vision

The Persistence of vision is a theory that an afterimage is thought to persist for around one twenty-fifth of a second on the retina,  this is believed to be an explanation for motion perception. The true reason for perception of continuous light is Flicker fusion.

 

 

A critical part of understanding the visual perception phenomena is that the eye is not a camera and in turn does not see in frames per second. In other words this vision is not as simple as light registering on a medium, because the brain has to make sense of the registers data the eye has provided and constructs a coherent picture of reality. Joseph Anderson and Barbara Fisher argue that the phi phenomena privileges a more constructionist approach to the cinema.
