I had missed this Bricklin's essay: Our photos as an edited record of our lives. I had never heard a satisfying answer to the question everybody asks in France "Why do Japanese people always take a loooot of pictures ?! They shoot anything!" (I asked the question myself to some Japanese friends and did not get any answer, i think i surprised them with my stupid question ). In this essay we find: "What they were doing was putting together the story of their lives, and they wanted to add something famous and beautiful to it. As they tell the story of their trip they can have that important stop that they have in common with so many others. Their photo shows that they, too, experienced something great". "Taking a picture of someone is a way of paying them the compliment of saying "you are important to me".
