What happens when we scale things? Increasing or reduzing size may seem an innocuous practice which only changes the measurements of an object. But in fact, scaling provokes brutal breaks and uncanny tipping points where things become radically and irrevocably different. This is what the vision machines of film with its variable image sizes always tried to tell us: how things by being scaled can fall apart – a lesson perhaps not only about our perception but also about our fragile world at the verge of tipping points.
