It really is. This is how I know:
Went to the Street & Studio exhibition at the Tate Modern today. It’s an attempt at showing the history of urban photography, from the mid-to-late C19th to the present. Most of the photos were taken in New York, London, Berlin and other Western European cities. There’s also a fun interactive thing on Flickr, allowing you to submit your own urban portraiture for possible inclusion in a book. Now that would be exciting.
