Blowup (1966)
Directed by Michelangelo Antonioni

Film Synopsis

Thomas is a busy London photographer who, when he is not occupied with photo-shoots of glamorous females, is squatting in doss houses to obtain material for an art book.  One day, he is crossing a park when he can't help taking some photographs of two young lovers.  One of the lovers, a woman named Jane, is incensed by having her photograph taken and hurries after Thomas in an attempt to grab his camera.  Later, Jane visits Thomas in his studio, and demands that he hands over the film negative to her.  He intentionally gives her the wrong roll of film and proceeds to develop the photographs he wasn't supposed to have taken.  Enlarging the film, he notices a dead body lying in the bushes and nearby  a hand holding a gun.  That evening, Thomas heads back to the park and, sure enough, he finds the body of a man.  On his return to his studio, the photographer notices that the troublesome negative and prints have all mysteriously disappeared, apart from one - a large enlargement showing a grainy blow-up of the corpse...
