One of the problems of making portraits of strangers in the street is to get those emotions and feelings out, is to portray the true self and personality of that person. Because as soon as you point that big piece of glass to them they go blank.
Photographer Simon Clarke found a workaround to that, he captures portraits of people as they ride public transports. In those places people are dislocated from their surroundings, they look into the void as they await to get to their destination, their thoughts expressed in their faces.
Sometimes you find the best portraits in the most uncommon places.
