Two virtues of a street photographer are anticipation and patience. Analyzing a scene and people’s behaviors will allow you to anticipate what will occur next. Obviously, one of the beauties of street photography is that a scene never unfolds exactly like you think it would. Yet, in some cases, you’ll correctly guess. You then just need some patience for it to happen. In the case of the picture taken downtown Buenos Aires, the eyes and posture of the girl provided for an easy guess.
