I have noticed that some photographers, who are obviously trying to do some street photography, position themselves at a busy corner or big square and wait there for the things to happen. Mostly they are the “shoot from a distance” type. Maybe they have just found a spot where the light is beautiful, or they like the background and now want something to fill the foreground. I’m not convinced that works out well, it is like deciding for yourself “today I want to take a photograph that expresses this or that”. If you move around it’s easier to remain open and attentive, you can get into a “rhythm”, there are more chances and you develop a certain intuition for hot spots where “things happen”.
