There are lot of opportunities to take photographs. Most deal with the benin, as a record of moments soon to be past. We collect the instant, we share them with those we think might care and we forget them. The cemetery of images past used to be a shoebox, it is now an old hard drive or dusty CD's. There are very few opportunities to photograph what goes beyond the meer exercise of recoding an event but rather permanently impact humanity's psyche. Yet, week after week, talented photographers worldwide seem to do it with ease and simplicity. They create, with their photographs, a collective memory. And although we weren't there, we all have the same feeling that it happened in front of our eyes. We integrate their images as if they were part of our lives and share the memory of them with others, as if we were all there, at the same time and at the same place. Some will make some of us act while others will make us smile, cry, cringe or sympathize. None will leave us indifferent. This week's selection confirms that from the heights of the International Space Station ( 2001: A space odyssey anyone ?) to the glossy pages of Dazed and Confused Magazine, from the flatland of Oklahoma to a sport stadium in Miami, there has been great opportunities taken to add content to our collective memories . And we feel so much richer for it.
