Mario Testino has photographed everyone from Joan Smalls and Gisele Bündchen to Jay Z and Jennifer Lawrence—plus, he’s lensed countless covers and editorials, for everyone (and we mean everyone) from V Magazine to Vanity Fair. The legendary Peruvian photographer was not, however, on Instagram—until now, that is. We well know that if there’s any place to leak behind-the-scenes footage, it’s on the Internet. And with his esteemed roster of collaborators, who knows what filtered finds Testino’s account might bring. Needless to say, he deserves a “Follow.”
