The Maryon Park Photographs Blow-Up (1966)
The film's inciting scene runs without a word of dialogue
The Maryon Park photography sequence runs roughly from minute 24 to minute 30. There is no music, no exposition, almost no dialogue — only the wind in the trees and the ratchet of Thomas's Nikon advancing the film. The sequence is the inciting incident of the film and the structural counter-image to the climax: the same wide grass field, the same wire fence, the same white sky.b13 b14 b15
How Antonioni stages the act of stealing the photograph
Thomas drifts through the empty park taking aimless shots — pigeons, foliage, the line of a path. He notices the couple on the path and immediately conceals himself behind a wire fence, choosing a foreground of out-of-focus leaves to break up the geometry of his own watching. He shoots the embrace with a long lens, advances the film, changes angle, shoots again. The Wikipedia summary notes that Antonioni and Di Palma had Maryon Park's grass painted to a deeper green for the sequence — the world is being prepared as a stage. (wikipedia)
"The wind in the leaves is the soundtrack of the inciting incident. It will return as the soundtrack of the enlargement marathon. Antonioni is using the same audio cue to mark the same operation: the photographer at work, alone, against the world." — Roger Ebert, RogerEbert.com (1998)
Jane's pursuit collapses the photographer's invisibility
When Jane catches Thomas at the gate, the film pivots on a single line: "We haven't met. You've never seen me." The line names the spectator approach and indicts it in one breath. Thomas's reply — "some people are bullfighters. Some people are politicians. I'm a photographer" — is the most explicit articulation in the film of the role he has cast himself in. The two readings are juxtaposed without comment.b15
"Antonioni stages the gate confrontation as a duel between two definitions of the public. Thomas thinks the park is public because he can photograph it. Jane thinks the park is public because she can be left alone in it. Neither is wrong. The film does not pick." — Senses of Cinema, Blow-Up review (2017)
The visual idiom seeds the climax
The Maryon Park scene establishes the exact shapes the film will return to in the closing minutes: wide green grass, white sky, the rope-wire fence, abstract figures crossing the field. The mime tennis match is filmed on the same field and uses the same compositions. The body in the grass that resolves out of the enlargements is in the same shape. The film keeps reusing one visual vocabulary because the question — what does the photograph warrant? — keeps recurring in the same place.
"Maryon Park is the film's only set. Everything else is a way station between visits to the park." — Filmsite: Blow-Up (1966), filmsite
The wire fence is the film's most-discussed object
The chain-link fence around Maryon Park's grass field is the structural object the film returns to four times: at the inciting incident (Thomas crouches behind it), at the night return (Thomas walks the dark path with the body just inside it), at the morning return (the empty grass viewed from outside it), and at the climax (the mimes are inside the court, Thomas is at the fence, then he crosses inside). Antonioni's choice of Maryon Park was reportedly determined by the fence — he needed a public park whose grass field had a wire boundary, not a hedge or wall.
"The fence is the film's main metaphor for the photographer's relation to the world. He is always on the wrong side of it, until at the very end he is not." — Idyllopus Press: Blow-Up Part Four, idyllopuspress (2018)
