The American fine art photographer Tina Barney is known for giving us a glimpse into the soul of her subjects, deftly capturing a passing glance, a wistful gaze or a confident look. The artist has been honing that singular perspective from behind her traditional tripod set-up for more than four decades. As her exhibition "Family Ties" goes on show at the Jeu de Paume gallery in Paris, she speaks to us about returning to familiar subject matter, documenting the rites and rituals of the American upper classes and why she thinks the Instagram age is "pretty horrific" for photography.
