High resolution visualizations created with custom software using 2.3 million Instagram photos from 13 global cities. Together with Nadav Hochman and Jay Chow.

How can we visualize millions of photos taken in New York, Bangkok or Tel Aviv in such a way that cultural differences between these cities can be revealed? How can we read the “stories” made up by the users’ sequences of photos? Phototrails is a research project that uses media visualization techniques for exploring visual patterns, dynamics and structures in user-generated photos. Using APIs provided by popular media sharing services, we crawled millions of publicly shared photos and their metadata. We analyze every image and then visualize groups of images together using our software tools.


"The Aggregate Eye: 13 cities / 312,694 people / 2,353,017 photos," together with Nadav Hochman and Jay Chow.
