"On City Streets" is a selection of street photography from various cities, including Hong Kong, Singapore, and Bangkok. It belongs to an initial set of four photo-books, the others being "On Home Streets," "On London Streets," and "On Bangkok Streets." Elsewhere, the author has written extensively about street photography, for example in "Street Photography Is Cool," but here he shows the images without words. As in the others in the series, even the titles have been confined to the back of the book.
