In street photography it is all about the moment and selecting just the right time to depress the shutter button. I saw this setting and thought it was interesting but didn't take a shot - it was missing something. A little later I went back to have another look and there were people - now it was interesting. I put the camera to my eye and took a couple of shots but they were all the back of peoples heads. I stay with the camera to my eye and under my breath said turn your head, and that's exactly what this person did. The moment.
