Richard Renaldi asks complete strangers to pose for a portrait with only one stipulation:
The premise of this work is simple: I meet two or more people on the street who are strangers to each other, and to me. I ask them if they will pose for a photograph together with the stipulation that they must touch each other in some manner. …. Touching Strangers encourages viewers to think about how we relate physically to one another, and to entertain the possibility that there is an unlimited potential for new relationships with almost anybody passing by.
The boundaries of personal space, captured.
