This street photo is spectacular for many reasons.
For me, it come together because of many photographic aspects:
1) It is genuine street photo. It clearly is not staged. 2) Two themes going on: Ties and color. 3) Geometry: the lines from the street signage and the vertical ties 4) Body movement: Red tie guy with left arm forward and yellow tie man with left arm back = nice contrast! 5) Color: Red tie, red street sign, and red car. Yellow tie, yellow street signage, yellow building. Nice contrast again! 6) Some much going on with facial expressions!
Interesting that the common thread is facial expression - all are frowning in what appears to be a flow of commuters. The one in front seems to be nervously gauging the distance of traffic behind him as if he's worried about the contents of the briefcase.
I know what you mean. I would think that single shots would draw less attention to yourself as well.
Burst mode is essential in sports, but the reality (that they don't tell us about) is that burst mode only works at its maximum rate under perfectly ideal conditions. Poor (read: normal for indoor sports) conditions lower my frame rate....pretty drastically. I get about a shot a second....maybe two if I am REALLY lucky.
