Wired Magazine has published a feature on Richard Renaldi's Touching Strangers series:
"The subjects’ spontaneous poses and reactions range from intimate to awkward, tender to taciturn, and they often betray the complexity and range of emotions human touch often elicits. A big part of the process was directing his subjects to interact in a way that looked interesting but also challenged them. Some were reluctant, even opposed, to participate. Some people didn’t have time; others backed out at the last moment, overwhelmed with discomfort or impatience."
