Photography's founding promise was that one look would be enough. The camera arrived as a machine for evidence, and for a century and a half we mostly let it testify. The 57th Rencontres d'Arles, on view across the city until 4 October, is built on the opposite skill. Its theme — Des mondes à relire, worlds to reread — sounds like curatorial politeness until you walk the forty-seven exhibitions and realise the argument is serious: the interesting act is no longer taking the picture. It is reading it again.

The festival announces this on its own poster. Carlos Idun-Tawiah's image of a young Ghanaian man on a bicycle, family strolling behind, radiates the warmth of a family snapshot — and is staged down to the last gesture. A fiction wearing the clothes of a document, chosen as the face of a festival about looking twice.

The director who stopped directing

The quietest revelation comes from a man famous for total control. Park Chan-wook storyboards every frame of his films; On a Quiet Morning, his first exhibition of photographs, fills the top floor of Lee Ufan's Tadao Ando–restored townhouse with fifteen years of pictures taken with no purpose at all — closed café parasols standing like melancholy ghosts, corners of things that caught his eye. Like the young Kubrick prowling New York with a Graflex, a director's instinct survives even when the directing stops: the frames still imply stories they refuse to tell.

Reading other people's memories

The rereading turns literal in the festival's strongest rooms. Lee Shulman's Anonymous Project has amassed roughly a million amateur Kodachrome slides; with the Senegalese artist Omar Victor Diop he restages them so that Diop himself appears inside the sunlit barbecues and birthdays of 1950s white America — a guest history never invited, smiling from within the archive. Clément Cogitore's Memory Palace runs four hundred hours of post-war home movies through artificial intelligence to ask what a society chooses to keep. And We Are Not Alone, Philippe Baudouin's history of UFO photography, traces our “culture of visual doubt” back to the nineteenth century — a reminder that the unreliable image is not an invention of the AI age, merely its rehearsal.

The year without its giants

Not everyone left persuaded. The centenary tribute to William Klein was pulled at the last minute over venue safety — a genuine loss. French critics called the edition thin on great names, saved by its emerging scenes; one English review shrugged at cute animals and alien abductions. The complaint is accurate and misses the point. A festival founded in 1970 by Lucien Clergue and his allies to prove photography deserved the status of art has won that argument so completely that it can now afford the harder one — teaching a public that photographs everything to trust its second look more than its first.

The tenderest proof is also the oldest. Martine Barrat, ninety-three, fills the Espace Van Gogh with the Harlem and South Bronx she filmed and photographed from inside, over decades, with the patience of other eyes the canon took too long to read. Her pictures were never news. Reread now, they are the whole argument: attention, given long enough, becomes a form of love — and love is the one reading a photograph cannot fake.
