The idea: The One Hundred Strangers project is a learning group for people who want to improve the social and technical skills needed for taking portraits of strangers and telling their stories. The method is learning by doing.
The challenge: Take 100 photographs of at least 100 people you don't know. Approach a person or group of people and ask for permission to both take a photo of them and to post it to the 100 strangers group. Get to know your subjects. Who are they? What is their life like?
