Photokina, the photography “show of shows,” opens in Cologne, Germany on September 20. The size of this biennial event is monstrous—you have to experience it to believe it. In 2014, a total of 1,074 exhibitors from 51 countries hosted 183,297 attendees. We’re taking serious show here. In honor of Photokina, here’s a pop quiz to test your knowledge of photography.
