Holger Biermann must be one of Berlin’s most active street photographers. When I go out for my photo walks I meet him every now an then on Friedrichstraße, Alexanderplatz or whereever. Currently he is showing parts of his Terrassen am Zoo series at FENSTER61 until Aug. 13. If you like it be sure to get his nice booklet of the same name that he sells for only 5 Euros.
