Retrographer harnesses the knowledge of the community to create a collaborative map of Pittsburgh's historic photographs.

How it works?

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.

About The Project

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.

Just Pittsburgh?

It doesn't have to be. If you would like to bring Retrographer to your city, and are able to work with an archive or museum to get access to a collection like Pittsburgh's City Photographer Collection, shoot me an email!

    "The Endness Street steps are visible if you look directly above the man standing near Saw Mill Run. These were wood then, but were replaced by concrete steps in the late '40s. They are (mostly) still there in 2023."
