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!

    "I must admit that the subgrade materials were not bad but there are not too many roads around that are still in good condition 109 years later. "

    "I've noticed this too. I think 100 years ago the green had trouble thriving in this environment. Think of all those pitch black Pittsburgh at Noon photos from the 30s, if people can't see the light trees can't be getting all of what they need. "

    "I believe the view of the old photo is actually one block further to the south where Forbes and Schenley intersect as opposed to the Northumberland intersection. :-)"

    "I admire these old concrete arch bridges of the early 1900's. I worked on the seismic retrofit of the Colorado Street Bridge in Pasadena, CA which had similar architecture. The difference in the view corridor mattered back then I guess. "
