I have looked at the work of Gursky and Ruff (his andere Portrats) but I had not really seen the work of Struth. In the true tradition of the Becher school, this is evenly lit and geometrically composed work that would look really great blown up and hung on a gallery wall.
The documentary traditions are to me more evident in Struth’s work (is that because the images are black and white? Or because they show street scenes and contain a wealth of narrative detail?) it is certainly not militant, more like taxonomic eyewitness.
