Instagram launched in 2010. In its early years, it was quite different from what it is today. In 2012, we began downloading posts shared in various cities over a specific period of time - several days to several months. We used official Instagram API which allowed such downloads until 2016).
Here are three visualizations - each shows 50k images shared over a few days within a 5x5 km area in San Francisco, Bangkok, or Tokyo. Time: from 2.5 to 5 days. This represents about 20% of all Instagram posts shared in these places during this period.
The radius represents the average color (hue), and the average lightness determines the angle.
High-res originals can be downloaded from Flickr (6000 × 6000) - follow project link below.

Project info:
Phototrails is a research project developed by Lev Manovich, Nadav Hochman and Jay Chow developed. We downloaded and analyzed over 2.3 million publicly shared Instagram photos from 13 cities worldwide.
The project uses experimental media visualization techniques to explore visual patterns, dynamics, and structures in user-generated photos, examining both metadata (upload dates, filters, geolocation) and visual content (hue, lightness, contrast).
Phototrails was the first academic study of Instagram’s large-scale visual data, with findings published in First Monday in July 2013.
