Photo of the weekPatrick came through with a cracker this week and it was always going to be one to beat. Federico emphasized that the success was due to Patrick's remaining visually alert and recognising a fleeting moment as it happens, which, as we all know, is quite a skill when it comes to street photography. Photo by PatrickEditor's note: Just to add to Patrick's winning image, it's actually a pretty good lesson in an old street photography trick. That trick is to find a scene that you like and then wait for somebody interesting to walk in front of it.
