Setting the stage with street photography, becomes a matter of finding the stage, then waiting for the actors to enter.
Melbourne tends to throw up a lot of these “stages”.
Timing is all. Being there at a good time, waiting then grabbing any moments that move you. My standard operationg proceedure tends to be wander, see, grab, which misses the main point, patience. Occassionally, I get lucky, often I have to compromise.
