One of the greatest skills for a street photographer is the ability to anticipate. Picking out a stage, knowing who the players are and how the scene will unfold is crucial to capturing exactly what you envisioned.
For this photo in the old part of San Juan I noticed the girl walking from the right as well as the person walking towards the darkened hallway. I set the stage and anticipated when both players would be in the location I wanted to capture. (You can click on the image to see a larger version)
Having the ability to know people’s intentions has played a big part in my urban and street photography. I am able to know when an image will come together that I would like to capture.
