ABSTRACT
As cinema is considered a primarily visual art, it is a rather counterintuitive thought that many things in films stay under the threshold of visibility, and many others cannot be grasped in their entirety because of the never-ending movement of the film. Cinema itself was based on the—known at least for half-century before its emergence—phenomenon of the persistence of vision, according to which for a few milliseconds an afterimage persists on the human retina. This phenomenon is responsible for rendering the gaps between the subsequent film frames “invisible” to the viewers.
