Paris Photo returns to Los Angeles on May 1 for its third year — this time headed up by the newly appointed director team of Florence Bourgeois and Christoph Wiesner. Seventy-nine exhibitors — that is, 70 international galleries and nine booksellers — will set up at Paramount studios to show their top photogs, including 39 single-artist presentations and 20 booths devoted to “young galleries,” from Tehran’s AG GALERIE to LA natives Little Big Man.
