If you're not familiar with the event, Wiki Loves Monuments is a photo campaign that lasts through September, where individuals contribute photos of registered historical sites to the Wikimedia Commons. So far in the United States, we've had 7,800 photo uploads by over 1,600 individuals. More info on the event is available here:
Judging takes place in October, and includes 3 rounds of judging by community members. An overview of the timeline can be seen here:
The first round of judging involves each judging judging a few thousand photos (last year was ~1,700 photos). It sounds like a lot, but it's a quick yes/no to each photo on whether or not it should continue to the later rounds.
Round 2 is more refined, with each judge reviewing < 500 photos on a 1-5 scale. Finally, with Round 3, judges rank the top few dozen photos to determine the top 10.
If you or anyone in your network may be interested in judging, please let me know (I'm happy to reach out to them if you'd like). Anyone with an eye for photography and a passion for historical preservation is a great fit - in particular, we're thrilled to have GLAM folks getting involved. Judges will receive some swag (t-shirt, stickers, etc.) as a thank you for their time.
