Thank you to everyone who submitted for the quiz. I haven’t had a chance to go through them all but here are the Photo IDs. What has been most revealing to me so far in the submissions I’ve looked at is the variety of photo knowledge that people have. Some people had no problem IDing Marina Abramovic or Ai Weiwei but missed Robert Frank and Lee Friedlander. Others correctly IDed Roger Fenton and Alexander Gardner but not Zhang Huan or Alfredo Jaar. The whole point of the quiz was to have fun, so I hope you did. All of the photos below are linked so click on them to learn more.
