You can see something of the same kind of thing in the color work of 1950s /60s Toronto photographer Fred Herzog.
You see this kind of thing too, elsewhere - e.g. W Eugene Smith in his photos of Pittsburg.
And photos of northern england by John Bulmer in the same time frame.
Or of course Fan Ho who did something of the same for Hong Kong.
