All of the photographs on the site come from the City Photographer collection hosted and curated by the University of Pittsburgh's Archives Services Center
Retrographer uses Google Maps to make it easy for anybody to geotag these images. This geotag data is sent back to the Archives Services Center to become a permanent part of the archive.
Retrographer was started in the Fall of 2010 as a project for the Senior studio Pieces taught by Dylan Vitone at Carnegie Mellon University. The project has evolved and lives on after the class has ended. So far over 3,900 photos have been tagged by people all over Pittsburgh
Retrographer continues to evolve. Check back soon on your smartphone, a mobile app is on the way.
