THE PERSISTENCE OF VISION
All film is essentially an optical illusion, a trick of the eye, which is known as ‘persistence of vision’. When the human eye sees an image, it retains it for a fraction of a second. If in that tiny space of time, one image can be substituted by another which is slightly different, then there appears to be movement! What you really see when watching a ‘movie’ is NOT really a ‘moving’ picture at all but a series of ’still’ pictures being shown in rapid succession. At the rate of 24 frames per second, the eye is easily deceived.
Animated film-making is fundamentally different from live-action film-making. The live-action camera captures a scene moving in real-time and freezes it into individual still ‘frames’ which are then projected onto the screen. In animation, there is no pre-existing motion. The camera captures stills that are either drawn, sculpted or created in a digital environment.
Animation is a complex and immersive art, with science as its backbone. It takes a great deal of practice and dedication for an artist to master it.
