There are photographers that want to achieve a goal with their photos, a goal that is not selling goods, decorating the living room or pursueing a hobby. There are many bright examples: 1. Lewis Hine helped with his photos to ban child labour in the USA. 2. W. Eugene Smith helped in a village named Minamata. 3. Ansel Adams was a 'treehugger' and contributed to founding national parks. Are there people around here that are interested in this kind of photography and think about their own projects?
