What is the typical format of the event?	Photography campaigns typically have one Call To Action (Upload Photos about X topic), but will frequently have local “contributing” campaigns that are organized by Wikimedia Affiliates that might include local photo walks and other in-person events or trainings.
How long do the campaigns last?	Most Photography campaigns last for 1-2 months in order to give time for photographers to identify and upload photos.
How do the organizers target the audience?	Photographers are targeted in two ways:  International Central Notice Banners are run on Wikipedias for readers and editors Local communities reach out to photographer communities in their own context
What is the typical impact of these events?	Content gaps Photos are upload of previously not photographed content Contributor gaps Photographers and new event organizers are easy to recruit through the campaign. Reader gaps - in theory, photographs improve reader usage of Wikipedia. But in practice organizers struggle to get images well used after campaigns.
Challenges	Organizers sometimes have challenges getting photographs used by the Wikimedia communities after the campaign. A separate campaign is sometimes needed to encourage contributions. Newcomers sometimes have trouble interpreting copyright or other requirements for quality images.
