It all started with Humans of New York, the 2010 blog project of street photographer Brandon Stanton who set out to create a "photographic census" of his city.
It's been an unreal success with over 600,000 followers on Facebook, thousands of portraits composed, and dozens of spin-offs launched around the world.
There's even a Humans of Miami project, started by Florida International University student Fay Goldstein, who writes:
Taking inspiration from Humans of New York (aka HONY) I decided that the people in the streets of Miami deserve just as much attention as New Yorkers do. Here is my chronicle one photo at a time.
When everyone thinks of Miami, they see crazy club scenes and sandy beaches. My home, Miami is so much more than that. Get a glimpse of the real 'Humans of Miami' here.
Goldstein started posting her own Humans of Miami portraits in April 2012, and she occasionally posts images from others via Facebook messages.
