Photographer Paul Batt is the eye behind these thoughtful - and thought-provoking - portraits of shoppers on escalators. As someone who's always found the experiencing of riding an escalator somewhat awkward - what do I do? where do I look? - I love the discomfort, and the mystery, and the curious sadness of the moments he's captured. Says Batt, "I tried to show longingness and the need for connection, as strangers randomly pass one another in opposing directions."
