My personal take on street photography is there's 2 types:
1. candid, natural photos of people doing everyday things - just what happens in real life, nothing staged. The skill is in framing, focusing and capturing the image
without affecting the image.
2. Capturing everyday scenes or ordinary things that are normally ignored to highlight them as the subject or in an unusual way (need not involve people).
I used to do enjoy street photography with my old OM-1 and a wide angle lens, prefocused and set exposure and just shoot from the hip. I had friends who sort of thought they were into photography with the latest fully auto cameras, who thought I was stupid, not even looking through the camera to take a shot, but sometimes to catch the moment there is no time... and I don't like people in posed photos much...
. Its a challenge to get a natural expression or a fleeting moment. Eventually I won them over when they saw the shots.
