I recently did a short photography course. 12 hours over six weeks (one evening a week). I have, as a result, packed most of my cameras away acknowledging my weaknesses. I will still take some photos of family and in a project to document graves in an historic cemetery, but will not consider myself to be a photographer any longer. Thinking of the works of St Ansell Adams has convinced me of that.
Having said that, a member of the tanknet facebook page has pointed me to these websites, that are worth reading.
