A cultural stroll through Paris with photographer Nikos Aliagas and writer Jean-Paul Enthoven

This week in Paris des Arts, Valérie Fayolle hosts Nikos Aliagas, a TV presenter and photographer. He takes us to his exhibit on old age at the Musée de l’Homme. "A photograph is a hundredth of a second, sometimes a few tenths of a second. It’s nothing. You don’t steal time, you don’t stop time, but you acknowledge it," Aliagas says. We also meet Jean-Paul Enthoven, a writer and conveyor of emotions. He discusses his latest "Dictionnaire amoureux". "Happiness is like a horse running past and you have a fraction of a second to grab its mane," he tells us. Finally, we head to "Le Large", a new contemporary art centre on the outskirts of Paris. After its century-long industrial past, the île Seguin is beginning a new chapter in its history.
