Sometimes you grab a street shot of people and you get spotted yourself. This couple in Paris is just that scene. I was spotted, I saw this couple off in the distance walking toward me and using the Zach Arius technique of looking like I was shooting something else in the background and moving the camera to the subject. After realising I was spotted I just smile at them making contact and raise my camera to my eye again to take the background shot again. This gives the impression the shot I wanted inadvertently had them in the shot. They smiled and I assume just thought they were moving out of shot and not taking a shot of them.
