The faces of homelessness. Photos by TEDxRosario speaker Pachi Tamer, who uses Instagram to share his portraits of people who live on the streets of the world’s metropolises. 

In his talk, Pachi (@cachafaz) reveals how the project was born:

I was using Instagram like any other — taking pictures of a sky, a bird — until one day I met this man [living on the street]. I asked him for a portrait, gave him a dollar for the photo, and he told me his story.

Since that day, I focused on taking portraits of people in the street, uploading the pictures along with their names and sometimes their stories. In them, I found the family I was missing.

The faces of modern slavery: photographer Lisa Kristine documents the lives of people who are enslaved around the globe

Over 27 million people live in slavery today — a reality that is hard to believe and invisible to many.
After an encounter with an NGO dedicated to eradicating modern day slavery — Free The Slaves — TEDxMaui speaker Lisa Kristine dedicated her life to photographing people whose freedom is not their own.

In her talk, "Photos that bear witness to modern slavery," Lisa shares what she’s learned from over two decades photographing modern-day slavery.

Above, some of Lisa’s haunting photos from brick kilns in India and Nepal.
