Share your own Touching Strangers photographs with the hashtag #TouchingStrangers on Instagram or Twitter, and contribute to the Touching Strangers exhibition in New York. Photographs should be of people you don't know and who don't know each other, before the photo is taken, who you ask to touch each other for the picture.

Through May 15, Richard will be picking his favorites to show alongside his exhibition. Check back here often to see the latest submissions, and visit the Touching Strangers Facebook page to see Richard's favorites.
