Blow up Antonion Film / Cortazar Short Story

In the Antonioni film, a photographer, "Thomas (David Hemmings), blows up a photograph and discovers a hidden gunman in the bushes. Thomas initially believes his photograph saved an old man from being murdered but discovers later that the murder happened anyway. In the Cortázar short story, a photographer thinks he has captured the bittersweet seduction of an adolescent by an older woman only to discover to his horror that she is “pimping” him for a dirty old man waiting in a nearby automobile. In a further transformation, the photographer is drawn into the slow motion of the photo montage – now this is complicated becomes his camera, becomes the seduced boy and yet remains himself. It is while he is in this tripartite state that he is murdered by the old man and lies dead in the photograph staring at the sky as camera, boy and photographer are all rolled into one". Please discuss how both film and short story are meditations on æsthetics and morality. Please discuss how the idea of abandonment is central to the film as in structuring of people, objects, and ideas.
