Not only is there something for everyone at Photo London, the sixth edition of this international photography fair is taking place entirely online for the first time. The fair has more than 100 exhibitors—look for emerging galleries in the “Discovery” section—and 21 countries are represented, including the newcomers Israel, Argentina, Ghana, and Egypt. Photo London is all about the mix. Younger talents share the walls with contemporary masters like Shirin Neshat and Hassan Hajjaj. Museums ranging from the Met in New York to Amsterdam’s Foam and the Moscow Multimedia Art Museum partner with the fair. And, yes, there are historic photographs from masters such as Richard Avedon (Johannes Faber, Vienna) and Horst P. Horst (Staley-Wise, New York). The wealth of work is stunning. —J.V.
