Spring second
Just found this wonderful photo by Josef Koudelka on the very first page of Edward Tufte’s splendid Visual Explanations. It was taken on some certain late August 1968 afternoon during the Prague Spring when Russian tanks brought things to an end. Koudelka wanted to capture/prove that the streets were emptied of protesters at that very moment and helped himself by simply taking a picture of his own wristwatch with the street as visual context (or the other way around, as you like), thus creating a powerful image that uses photography with stunning awareness.
