Hi David, About fifty years ago I worked in an Amsterdam Photolaboratory. In my Holidays while riding through France on my little motorcycle in a village I passed a huge monument stating that in this village Nicephore Niepce had invented photography. After my trip I showed my colleagues in the laboratory a picture of this Monument. Nobody had ever heard of Niepce. Sad to say I remember it after nearly fifty years, I really was disappointed. Now I am succeeding in arousing far more than just a little enthousiasm in my own little family. Together with one of my grandchildren I am learning to make the emulsions of old. The tutorials on Denise Ross's The Lightfarm website are as inspirational as can be and a tremendous motivation for the younsters around me. More is not to be hoped for. Henk
