For its 15th birthday, North America’s leading photofestival takes on a new name. Momenta: Biennale de l’image is designed to denote a more studied approach than the previous Month of Photography identity and is entirely in keeping with the direction of the festival – in recent years, under the creative direction of artists, curators and academics including Joan Fontcuberta, Paul Wombell and Marie Frase, it has addressed themes such as the ‘post-photographic’ condition and the impact of automation in image-making. This year’s invited curator is Ami Barak, a French visual authority.
