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!

    "Just went down these steps today. (They're closed but I was able to make it all the way thanks to a board someone put in.) They are concrete now and are in rough condition. The "now" photo is what you see across Kilbourne St. when you get to the bottom."

    "I believe this photo should say "looking North." From the vantage of this photo, if we were facing West, there would be no bridge in the background. "

    "Directly next door to this site today (4331 Andover Terrace) is a split-level home built by Robert Lavelle, a prominent Black realtor in Pittsburgh beginning in the 1950s. Lavelle did a great deal to advance opportunities for home ownership for Black Pittsburghers when white-owned banks and realtors would not sell them homes."
