When I was 16 or 17 I undertook an evening course in photography at the local technical college. Much of what we did is a lifetime away - a technological lifetime as well as a human lifetime. Apertures and shutter speeds, ASA ratings and range finders - it's all the stuff of museums today. We also did a number of sessions on lighting - a subjects that is just as relevant in the days of digital images and pixels as it was in the roll film days of old. A model was employed by the college and this is one of the shots I took fifty or more years ago. I doubt whether I have taken a better portrait since.
