Le Flâneur (music by The XX) from Luke Shepard on Vimeo.
Check out Paris in 2000 images at National Geographic Traveler for an interview with Luke Shepard about this project.
A photographer strolling through a city can be thought of as le flâneur: an observer, someone perceptive, thoughtful, attuned to broader patterns and smaller exquisite details, mapping out the city on foot.
