When I’m standing at one of the tram stops in the city centre waiting for my transport home, I often take random shots of the action across the road.
It’s usually a couple of quick shots with little thought to composition or focus.
Every now and then I get a good shot, sometimes a Great Shot! (and sometimes a not-so-good shot).
But since every photo opportunity is a Great Opportunity (to practice Street Photography), none of the resulting images could possibly be a waste of time.
