The “Vertigo effect” (also called a dolly zoom) is one of cinema’s most unsettling tricks — because it isn’t CGI. The camera moves while the lens zooms in the opposite direction, keeping the subject the same size as the background warps and stretches. Hitchcock made it famous in Vertigo (1958) to visualise acrophobia and disorientation, and it’s been used ever since to show sudden fear, shock, or realisation — a moment when the world feels wrong. ##FilmHistory##Cinematography##VertigoEffect##Hit
