Hi Abdulmuhsen,
interesting question (so far all the questions you post about Street photography).
I love street photographs and I had to take a distance since you posted this, I wanted to think before answering and perhaps I am ready to tell you now.
I shoot in the streets for many years, either as a photojournalist in the past,
or as an amateur at present. I have to point out here that I am nearly 17 years away from the front line of photojournalism, now shooting only for pleasure.
As many other photographers, I mostly shoot at my comfort zone where I know the rules. Usually walking around the city at a slow pace looking around, probably taking a coffee, trying to "empty" the charge from other thoughts.
I don't shoot straight away, I try to feel the "mood" of the day first.
In my experience, my best shots were taken when I wasn't thinking about anything. Not even what is the subject. This is a bit difficult to explain, I can only compare it to the automatic reaction of a driver who needs to brake. You don't think about breaking, it comes naturally when you feel a danger.
Now this, maybe experience, I dare say a state of mind, is not there every time, I have to be in a "good day" to achieve it and only if I am inside my comfort zone. Something triggers my senses, something disturbs me and the shooting is automatic.
About confrontation, I had many of them when shooting demonstrations or sports, I was beaten some times by angry football fans and had many quarrels with the police and films ceased, but I don't recall having any confrontations in all my years of shooting street subjects. Usually, a smile smooths everything and in the rare cases someone sees my intentions and gives me the message, I respect it and don't shoot.
My experiences in Europe and Turkey are pretty much the same after getting accustomed for some time.
I presume it would be different to shoot in countries with other cultures like yours so I would be interested to know how you shoot in your country.
For me, Street shooting is a study of social behaviour, apart from been a creative photographic experience and I truly enjoy it much more than shooting any other subject.
