First round application

Wikimedia Finlands & Ajapaik's first round application

Ajapaik is an existing platform and mobile app for harvesting contemporary repeat photos or rephotos to historic pictures. The mobile app displays the old pictures semitransparently on top of the camera stream making it really easy to adjust historic captures with current landscape. Ajapaik users have already contributed almost 25000 rephotos to historic photographs thus creating a unique collection of additional pictorial content that enriches the historic photographs in public collections. Majority of the content on the platform is from Estonian and Finnish collections but the app needs scaling up to European level. Also a crossplatform application is in the making in order to substitute the current Android only application. Additional user engagement and traction mechanics need to be developed for the activity of rephotography to gain wider traction. The application already has integration with the European cultural heritage portal Europeana enabling access to thousands of historic images from all over Europe. Additional machine learning and computer vision technologies need to be implemented to enable easier discovery of relevant content for users.

The activity of rephotography has great potential in tourism. A lot of travel is about the history of places, it is very natural to contemplate historic photos of landmarks and historical sites. Taking contemporary rephotos connects the historic knowledge in pictures and personal experience. The other important target sector is education where rephotography can empower the learning activity.

Second round (26.6.2022)
