Sorry to have missed the recent event with John Benton-Harris in Norwich (http://www.wexphotographic.com/blog/events/2017-04-29-seminar-with-john-benton-harris/?utm_source=facebook.com&utm_medium=social&utm_campaign=John-Benton-Harris3). Reading of it took me back to May 1982 when JB-H lead a workshop on social documentary photography at the Cambridge Darkroom, at that time still housed in the Bath House.
